Abstract: 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.

Abstract: A sequential decoding method and a decoding apparatus are provided. According to the method, an open stack is adopted for storing a plurality of paths. When the codeword generated by an internal decoder in the decoding apparatus is incorrect, a codeword is generated again by using the paths stored in the open stack. Accordingly, the complexity of decoding is reduced.

Abstract: A method for BTFD decoding of signals having at least a message block of k-bit from a length candidate set S={s1, s2, . . . si}, wherein the k message bits are encoded by a CRC encoder and processed by an (n, l, m) convolutional encoder to generate encoded data that includes decoding a received frame to form a decoded sequence that includes an si-bit message and an error correcting code, calculating a ?(si) value, comparing ?(si) with a threshold value, repeating the decoding and calculating steps if ?(si) is greater than the threshold, and updating the threshold to be ?(si) if ?(si) is less than or equal to the threshold.
