Abstract :
An efficient parallel processing mode is proposed for fast decoding of orthogonal convolutional codes using the forward-only iterative belief propagation algorithm. This iterative decoding can approach the speed of one-step decoding while providing useful tradeoffs between decoding speed and error performance. The error performances of two convolutional self-doubly-orthogonal codes are obtained by simulation, and compared to their asymptotic performances
