A PARALLEL IMPLEMENTING METHOD OF ITERATIVE DETECT / DECODE RECEIVING IN A WIRELESS COMMUNICATION SYSTEM

摘要

A parallel implementing method of iterative detect/decode receiving in a wireless communication system, a implementing method in accordance with wireless transferring and receiving technology, that used in high speed wireless transferring technology field. Said iterative receiver includes four modules, a soft-in soft-out (SISO) detector module (10), a soft-in soft-out decoder module (12), an interleaver module (13), and a de-interleaver module (11). The SISO detector module (12) outputs a new soft information to the de-interleaver module (11) according to the soft information provided by the interleaver module (13) and a received signal. The SISO decoder module (12) reads the soft signal from the de-interleaver (11), and outputs a new soft information to the interleaver (13). The SISO detector module (10) and the SISO decoder module (12) are parallel operating at the same time, and data in the interleaver (13) and the de-interleaver (11) is updated in real time. When the iterative operation is finished, the SISO decoder module (12) outputs decision bits (14). It is possible to process data twice as much as that of the prior art within same period with the same hardware source.
