A decoding method and system for real-time wireless channel estimation, which decodes a received signal with a noise. The received signal is coded by a concatenation code. At first, the received signal is performed a certain amount of decoding by a Max-Log-MAP decoding procedure. Next, an estimated amplitude of the received signal and an estimated variance of a noise are computed. Then, the received signal is adjusted in accordance with the estimated amplitude and the estimated variance to thereby produce an adjusted received signal. Finally, the adjusted received signal is decoded by a Log-Map decoding procedure.
