Row above-mentioned steps 301-304, to be calculated according to multi-group data packet more using any two data packets continuously transmitted as one group
A prediction bandwidth counts multiple prediction bandwidth, and the statistical value of multiple prediction bandwidth is determined as transmitting terminal and receiving end
Between bandwidth.Wherein, which can be the average value of multiple prediction bandwidth, or may be multiple prediction bandwidth
The weight of weighted average, each prediction bandwidth can be determined according to the calculating time of prediction bandwidth, be got in current period
The data packet that evening receives predicts that the calculating time of bandwidth is more late, also can more embody current network condition, therefore will calculate
The weight of time later prediction bandwidth is set as higher weight, will calculate the time and predict that the weight of bandwidth is set as earlier
Lower weight.Alternatively, the weight of each prediction bandwidth can also be determined according to the variance of prediction bandwidth, according to multiple prediction
The variance of each prediction bandwidth of bandwidth calculation sets lower weight for the weight of the biggish prediction bandwidth of variance, to drop
Low influence of the network fluctuation to calculated result accidentally.
Certainly, the mode of computation bandwidth is optional way in above-mentioned steps 305, in fact, receiving end can not also execute
Step 305, directly prediction bandwidth can be determined as between transmitting terminal and receiving end after executing step 304 and obtaining prediction bandwidth
Bandwidth.
With directly will prediction bandwidth be determined as transmitting terminal compared with the bandwidth between receiving end, it is multiple according to what is be calculated
Prediction bandwidth is counted, and available more accurate bandwidth avoids influence of the accidental network fluctuation to bandwidth, into one
Step improves accuracy rate.
306, receiving end sends calculated bandwidth to transmitting terminal.
307, transmitting terminal receives the bandwidth that receiving end is sent, the code rate of setting and bandwidth match.
When maximal rate of the calculated bandwidth no more than setting, transmitting terminal sets equal with bandwidth for code rate, from
And it can fully utilize bandwidth resources.And when calculated band is wider than the maximal rate of setting, transmitting terminal sets code rate
It is set to maximal rate, so as to improve bandwidth availability ratio as much as possible in the case where guaranteeing data normal transmission.
After receiving end calculates bandwidth, the bandwidth is sent to transmitting terminal, then transmitting terminal can accurately determine current
Bandwidth is how many, also more than needed how many compared to code rate, therefore can disposably improve code rate, without detecting the adjustment width of code rate
Degree sets code rate to and bandwidth match, and is continued to send data to receiving end according to code rate adjusted, thus after ensure that
It can guarantee the normal transmission of data during continuous, and bandwidth availability ratio can also be improved.
In practical application, during transmitting terminal and receiving end transmission data, the period can be divided according to preset duration,
According to the multiple data packet computation bandwidths continuously transmitted in each period, matched code rate is arranged according to bandwidth, by constantly
Computation bandwidth simultaneously adjusts code rate, can be adjusted in time according to actual network condition, improve data laser propagation effect.
