CODE DIVISION MULTIPLEX TRANSMISSION SYSTEM, TRANSMITTER AND RECEIVER

摘要

PURPOSE: To allow a reception terminal to receive normal data in a short time from an optional transmission data sequence even when the reception terminal does not know in advance parameters required for reception of each transmission data sequence. CONSTITUTION: Parameter information such as a convolution code coding rate of each transmission data sequence and an interleave size that is spread by the same synchronizing spread code as a spread code used for synchronization processing for the spread code is multiplexed in time division on a synchronizing signal. Thus, the reception terminal can acquire the parameter information independently of the reception of each transmission data sequence so long as the synchronizing signal is received. Then the reception terminal sets parameters to each section of a receiver basede on the parameter information of each transmission data sequence to easily and quickly conduct the reception processing of each transmission data sequence.
