In order to solve the existing scheme of using wood in the wood, the first one is to provide a multi-forest method. The idea of this scheme is Lin Zuo, that is, each forest is pre-determined to determine the shape of the scheme. The method of covering the component force, the shaping scheme shown in Fig. 21 of the shaping scheme shown in Fig. 2, the covering of the second 22, is small, and the first and second residences are formed by the small and identical forming. The first 21 can cover 1, 2, 5, the first 21 of the small 1, 2, 3, 4, 5, 6 in the 1 The small indication 2 shows that, in other words, 11, 13, and 15 covering the small 1, 3, and 5 directions constitute the 21st, and the 21st cover is covered by the 11, 12, and 15 Covering the small representation 3 of the 22 coverage, which is 2, 4, 6, the second 22 coverage, that is, the 12, 14, 16 covering the small 2, 4, 6 constitute the second 22, And the second 22 covers are covered by 12, 14, 16 joints.

 Position of 30 position, position of 30

 The 21 or the second 22 is covered by the 21st or the second 22 Co. The small edge 30 is the same as the 30 pairs of each other. This method is shown in process 4, including

 Step 101 0 The reverse 31 letter indicates (ha e Q a y d o , C ) information, 30 on the small edge, and each other is small to provide each.

 The position of step 102 30 is positioned, the position of 30 is covered by the 21st, and the 21st 30th is combined.

Step 103: The received letters 31, 32, and 33 respectively analyze the primary small and small received signals, and the CQ and CQ of the small 41, the small 42 and the small 43 receive letters have at least CQ greater than CQ, and use Policy otherwise, use the policies of policy step 104, using the scenarios in each policy .

 In step 101, the position of 30 is different, and the difference is small. This is a small description of small 41 30, that is, 30 reverse 3 1 information. In addition to the 30 anti-31 C information, you can 30 to the small 41, the small 42 and the small 43 edge, and you can receive the signal energy (power) of 30, 31, 32, and 33, 30 is small 41, 42 small, 43 small If the letter receiving 0 is not strong, the description is 30 in small 41 small 42 and small 43 edge. It should be noted that the small letters that can be received by the nearby small ones have the strongest received letters, which is the same location as the small ones.

 In step 102, the CQ information of 30 can be reversed, the position of 0 is positioned, the letter of 30 can be received by 31, 32, and 33, or the letter of 30, 31, 32, and 34 is received, and 0 is the 21st or the Coverage of the 22nd, 30 coverage of the 21st, that is, 30 at 31 where the small 41 32 is located at the small 42 and 533 where the small 43 edge, 31, 32 and 33 provide each. 30 In the coverage of the 21st, the small edge 30 is the same as the small 41, the small 42 13 and the small 43 15 and 30.

 30 Coverage of the second 22, that is, 30 at 31, small 41, 32 at the small 42 and 34 at the small 44 edge, 31, 32 and 34 are provided. The small edge 30 is the same as the small 41, the small 42 and the small 44 12

Same as 30 lines.

In step 103, the value of CQ can be any of 0 to 30, and 0 represents Exceeding ". 0 of C in this case, if CQ 5 of 30 receiving small 41 is greater than 0, CQ 10 receiving small 42 is greater than 0, receiving CQ 0 of small 41 using each strategy 30, receiving CQ 0 of small 42, Then use each strategy. In the coverage of the second 22, the strategy is similar.

 The strategies in this section are shown as small 41, small 42 and small 43 with 30, and the strategy 5 of Co is shown in the strategy 5. In the strategy, Co is the same number, before the small 41, the small 42 and the small 43 are formed. To 31, 32, and 33, that is, the equal forces of 31, 32, and 3, 31, 32, and 33 use different shaping values, 31 uses the direction of 11 in the 21st of the 21 to cover 1, forming B, 32 Use the direction of 13 in the 21st to cover 3, shape

B, 33 The direction of 15 in the 21st used Coverage 5, Forming B 30 Received letter Representable

 y hBX+hB

 Wherein, the letter received by y 30 represents a letter matrix of 41 in the 21st, h represents a letter matrix of 42 in the 21st, and h represents the letter matrix of 43 in the 21st, the shaping of B 11 , the shape of B 13 , the shape of B 15 , the number of 31 32 and 33 .

 The received letter can be obtained as a matrix, a general matrix of shapes.

In the strategy 6 of the Co strategy, in the strategy, 30 small energy analysis, small (small 41, small 42 and small 43) component small and small, the strongest of the small 41 force small, small 42 Small 43 is small, about 31, 32 and 33, 31 Co, 32 and 33Co

 X, 31, 32, and 33 use different shaping values, 31 used in the 21st room of the 21st direction covers 1, 1 is shaped B, 32 uses the 13th direction in the 21st direction to cover 3, shape B, 33 The direction used in the 21st dimension covers 5, the shape B, 0 the received letter can represent y BX+hBX+hBX than the letter received by y 30, h represents the letter matrix of 41 in the 21st, h represents the 21 small 42 letter matrix of the first room, h represents the 21st small 43 letter matrix, B 11 shape, B 13 shape, B 15 shape, 31, X 32 and 33, Etc

 The equal matrix of X is hB+hB. The equal matrix, the matrix of X, etc.

 Before the 30th coverage of the 21st coverage of the park, the 30 received letter, if 30 is in the second 22 coverage, 30 received

 Not y BX+hBX+hB3X or y hBX+hB is different, indicating a letter matrix at 41 in the second 22, indicating a letter matrix at b 42 in the second 22, h indicating 22 in the second 22 The letter matrix, the shape of B 16 , the shape of 14 , the shape of B 12 .

In step 104, if 0 is over the coverage of the 21st, For each of the strategies 1, 31, 32, and 21 to 30 X, or 2 for each strategy, then 31, 32, and 21 to 0 and x.

 The coverage of the second 22 is the same as the execution, which is no longer the case.

 In the small margins, according to different separations, the fate of the fate, respectively, using the shaped wood

 Hugh plan. With the same strategy, and the CQ of the received letter, the strategy is taught, the scheme is beneficial to the improvement of the performance of the system, the location of the user, and the strategy of receiving the good signal, which effectively improves the overall performance.

 The second provided by this is the multi-system, 7 is shown, including

 The determination 201 is such that the user terminals are smaller than each other at a small edge 202, and the user terminals respectively using different directions in the same wave are different, and the same wave is composed of the small overlaps.

 The step of arranging includes locating 203 for positioning of user terminals that are small to each other.

The cells are small to each other 202, close to the coverage of the root wave of the root user terminal, and each of the user terminals having different directions in the first wave is used, or the position of the user terminal is covered by the second, and the second is used respectively. The number of user terminals in which the directions are different from each other is different, and the coverage in the first wave is small and the coverage in the second coarse is small. Steps: 202 are smaller than each other, and at least the message indicating that the user terminal receives the message is greater than □, then the user terminals are more, and the same is to the user terminal; otherwise, the user terminals are more, and the number of the user terminals is more 5 The same and different to the user terminal, and the user terminal has the highest received letter indicating that the user receives the message.

 Steps, which are relatively small 202, are nearly the same as the user terminal, and the trust and power to the user terminal y hBX + 0 hB , otherwise, the user terminal is sent a letter and force y hBX , where B+hB . Step 201, near the root user terminal reverses each other's 202 indication that the user terminals are at a small margin to each other.
