Performance analysis of threshold decoder with feedback for self-orthogonal convolutional codes
Bit error performance of a threshold decoder with feedback for self-orthogonal convolutional codes are analyzed. The difference triangle method is applied to determine the effect of feedback for consecutive decoded symbols. Instead of stochastic method proposed by Morrissey, the difference triangle method is faster, easier and implementable for any constraint length convolutional codes with large correcting capability. The analytical results show more closer estimation of error probability than that of Genie and definite decoder for same codes at high Eb/N0 region.
