An error performance analysis of iterative threshold decoding

A method for analyzing the error performance of the iterative threshold decoder using strict sense multiorthogonal convolutional codes where the multiplicity order is larger or equal to the number of iterations is presented. This allows a tractable analysis, since all random variables are considered independent at each decoding step. The analysis provides a good prediction of the error probability convergence value of the iterative decoding process using strict sense doubly orthogonal convolutional codes.
