Claims (5)

1. Система передачи множественного доступа с кодовым разделением каналов, содержащая по меньшей мере передатчик, включающий в себя средство для формирования кадров, причем полезные данные подаются на упомянутое средство в цифровой форме, упомянутые полезные данные делятся на блоки данных и сжимаются для формирования пакетов данных, причем каждый пакет в кадре характеризуется временной длительностью (td) и внутрикадровым начальным моментом (t0), средство для расширения пакетов данных с помощью кодовых последовательностей, средство для управления мощностью, посредством которого управляется мощность упомянутых расширенных пакетов данных, и средство для регулировки упомянутой временной длительности (td), упомянутого внутрикадрового начального момента (t0) и передаваемой мощности.1. A code division multiple access transmission system comprising at least a transmitter including means for generating frames, the useful data being digitally supplied to said means, the useful data being divided into data blocks and compressed to form data packets, moreover, each packet in the frame is characterized by a time duration (t d ) and intraframe starting moment (t 0 ), means for expanding data packets using code sequences, means for power control, by which the power of said extended data packets is controlled, and means for adjusting said time duration (t d ), said intraframe starting moment (t 0 ), and transmitted power. 2. Система передачи множественного доступа с кодовым разделением каналов по п.1, отличающаяся тем, что средство для расширения данных с помощью кодовых последовательностей предназначено для выбора коэффициента расширения в зависимости от соответствующей первоначальной скорости передачи полезных данных.2. The code division multiple access transmission system according to claim 1, characterized in that the means for expanding data using code sequences is intended to select an expansion coefficient depending on the corresponding initial useful data rate. 3. Система передачи множественного доступа с кодовым разделением каналов по п.1, отличающаяся тем, что средство для регулировки переменных внутрикадровых начальных моментов (t0) пакетов предназначено для регулировки внутрикадровых начальных моментов (t0) пакетов в зависимости от размера ячейки.3. The code-division multiple access transmission system according to claim 1, characterized in that the means for adjusting the variable intra-frame starting moments (t 0 ) of the packets is designed to adjust the intra-frame starting moments (t 0 ) of the packets depending on the size of the cell. 4. Система передачи множественного доступа с кодовым разделением каналов по п.1, отличающаяся тем, что содержит средство для определения временных интервалов кадра, используемых для передачи данных, в зависимости от распределения измеренной напряженности поля в кадре.4. The code-division multiple access transmission system according to claim 1, characterized in that it comprises means for determining the frame time intervals used for data transmission, depending on the distribution of the measured field strength in the frame. 5. Система передачи множественного доступа с кодовым разделением каналов по п.1, отличающаяся тем, что за счет использования дуплексного режима с разделением по времени обеспечено разделение двух направлений передачи соответственно нисходящей и восходящей линии связи.5. The code-division multiple access transmission system according to claim 1, characterized in that due to the use of time division duplex mode, separation of the two transmission directions, respectively, the downlink and uplink, is ensured.
