Concatenated coding scheme employing soft decision for outer codes-DSD (double soft decision) concatenated coding system

Improving concatenated coding communications by employing signal editing techniques

“…The purpose of this investigation was to examine the error location performance from the rate-1/2 Viterbi decoding process and its output, where each computer run was 500,000 bits long. There are two key performance parameters: A = (number of bits deleted by a specific error location technique)/(total number of bits in one run), which is used to estimate the efficiency, and 6 = (number of error digits deleted)/(total number 6 for various values of X, Y, 2, n, and n,, with n, = 15: metric differences (the unit for both A and 6 is per cent) SER: of error digits before error deletion), which is used to estimate the accuracy. In the following, we shall summarize our computer simulation study results.…”
