Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] 1. Realization of joint source-channel arithmetic code decoder.
[0022] (1) Joint source-channel arithmetic code decoding based on maximum a posteriori probability algorithm
[0023] Suppose the source symbol sequence a={a of length N 0 , a 1 ,...a i ,...a N-1} becomes a binary sequence b={b 0 , b 1 ,... b S-1}, then enter the CABAC binary arithmetic code (variable length code) encoder, the output length is the binary sequence x={x 0 , x 1 ,...x M-1}, followed by binary phase shift keying (BPSK) modulation and channel coding into a sequence y={y 0 ,y 1 ,...y M-1}, sent to the AWGN noise channel, the sequence received at the receiver is Soft output information obtained by channel decoding It can be considered as the x-sequence through the noise channel. The maximum a posteriori probability algorithm code decoding is gi...
