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.
