Cdma reception apparatus and error correction code symbol soft decision method

摘要

Demodulated symbol data obtained by RAKE combining a multi path is subjected to a symbol soft decision, and at the same time, a reception state is detected from the demodulated symbol data. The demodulated symbol data after the symbol soft decision is delayed, and at the same time, an optimum mapping table is set based on the reception state detection result, whereby the demodulated symbol data after delayed and subjected to the symbol soft decision is again subjected to the symbol soft decision.
