• 論文の詳細を見る

• This letter presents a method of finding the optimal quantization stepsize that minimizes quantization loss and maximizes coded BER performance. We define 'Information Error Rate'(IER) and obtain the equation of the modified constraint length (K_m) to obtain an upper bound of coded BER performance of a l bit quantized soft decision Viterbi decoder. Using IER and K_m, we determine the optimal quantization stepsize of a 2 bit and 3 bit quantized soft decision decoding system in an AWGN channl with respect to SNR, and verify our strategies by simulation results.
