A DATA TRANSMISSION METHOD, CDMA TRANSMITTER, AND CDMA RECEIVER

摘要

The invention relates to a CDMA transmitter and CDMA receiver and a data transmission method for transmitting a digital signal, the method comprising interleaving the signal to be transmitted prior to transmission and deinterleaving the received signal. To reduce the effects of interference caused by the transmission path, in signal interleaving in the method of the invention the symbols are divided in the time domain into elements substantially smaller in duration than the symbols, and a given number of such elements are regrouped in a new order, and the symbols to be tramsitted are formed of these rearranged elements, and in deinterleaving the symbols received are correspondingly divided into elements, said elements being regrouped in the original order.
