Изобретение относитс к радиосв зи и может быть использовано в системе св зи сотовой структуры.This invention relates to radio and can be used in a cellular communication system.
Цель изобретени - повышение эф- фективности радиосв зи путем расширени зоны обслуживани при сохранении числа базовых станций.The purpose of the invention is to increase the efficiency of radio communications by expanding the service area while maintaining the number of base stations.
На фиг. 1 и 2 изображены зоны радиосв зи в моменты времени t« и t соответственно.FIG. 1 and 2 depict radio zones at times t "and t, respectively.
Базовые станции 1 с помощью узко- направленных антенн 2 - фазированных антенных решеток, синхронно просматривают обслуживаемую территорию таким образом, что последовательно облучают сотовые чейки ,..., Splr-S, где п - число сотовых чеек в зоне повтор емости. Если обозначить облучаемую соту k базовой станцией (в примере k 1, 2, 3) в момент времени tj , , п за 9 i , то элементы последовательности могут быть представлены в видеBase stations 1 using narrow-directional antennas of 2-phased antenna arrays synchronously scan the serviced territory in such a way that cell cells are sequentially irradiated, ..., Splr-S, where n is the number of cells in the repetition zone. If we designate the irradiated cell k by the base station (in the example, k 1, 2, 3) at time tj,, n for 9 i, then the sequence elements can be represented as

Таким образом, S- - i- сотова чейка в зоне повтор емости. Пусть период обзора (врем облучени Ьсей территории) равен Т0, тогда врем облучени каждой сотовой чейки u t T./n т.е. кажда сотова чейка облучаетс в течение времени ut. Передача информации в рассматриваемойThus, the S-i-cell is in the repeatable area. Let the review period (the irradiation time of the Ls territory) be T0, then the irradiation time of each cell u t T./n, i.e. each cell is irradiated for a time ut. The transfer of information in question

Т0 125 мкс, а за врем ut передают один отсчет речевого сигнала . При работе в нереальном времени в цел х простоты практической реализации положим Т0 кратным 125 мкс, т.е. Т0 1-125 мкс, где 1 - некоторое положительное целое число. В этом случае за врем ut передают 1 отсчетов речевого сигнала.The system is implemented in digital form. If such information is a voice message, then in real-time operation Ta 1 / 2Fft, where FB is the highest frequency in the spectrum of the speech signal. T0 125 µs, and during the time ut transmit one sample of the speech signal. When working in unreal time for the sake of simplicity of practical implementation, we set T0 to be a multiple of 125 µs, i.e. T0 1-125 μs, where 1 is some positive integer. In this case, during the time ut, 1 samples of the speech signal are transmitted.
Представим сигнал, которым передаетс один бит информации, на входе приемника подвижного объекта в виде:Imagine a signal that transmits one bit of information at the input of a moving object receiver in the form:
