Viterbi Decoding for Convolutional Code over Class A Noise Channel

摘要

Power line channel often suffers from impulsive interferences generated by electrical appliances. Therefore, power line communication (PLC) suffers the degradation due to such the impulsive interferences. Middleton's Class A noise model is frequently utilized for the modeling of such the impulsive noise environment. In this paper, we deal with the Viterbi decoding for con-volutional code over additive white Class A noise (AWAN) channel. We propose a Viterbi decoder for convolutional code optimized in AWAN channel. In addition, we show the performance of the proposed Viterbi decoder for convolutional code in Class A noise environment by computer simulation.
