Parameters Optimization of the Multithreshold Decoders for Non binary Error Correcting Codes

Abstract

Efficiency of symbolic multithreshold decoders (qMTD) for non-binary self-orthogonal codes in q-ary symmetric channel with alphabet size q are analyzed. It has been shown the bit error rate performance of qMTD depends on many discrete variables. A new optimization algorithm for minimization of the decoding function on the alternating variable descent method base  is proposed. Simulation  results  shown new optimized scheme can offers better performance.
