  • Abstract
    The sensitivity of the iterative maximum a posteriori probability (MAP) decoder to the initial channel values is investigated and a simple adaptive signal-to-noise ratio (SNR) algorithm operating within the delta variances from two MAP decoders is proposed. It can improve the BER by about 0.3 dB without much additional hardware complexity.
