Time division multiple access communication system, signal receiving method in time division multiple access communication system, and center unit for use in time division multiple access communication system

摘要

The present invention relates to a time division multiple access communication technique. A center unit for time division multiple access communications with a plurality of subscriber units comprises a channel receiving section for receiving a synchronization establishing signal with a variable receive timing, from each of the subscriber units as a varying channel signal and further for receiving, as a fixed channel signal, a communication signal from the synchronization established subscriber's unit at a constant timing, and a control section for controlling the receive processing in the channel receiving section so that the varying channel signal is receivable within a period for receiving the fixed channel signal.
