Abstract :
This paper shows that orthogonal coding and iterative decoding improve coding gain. The encoder maps a block of data into a block of bi-orthogonal codes. The decoder is a correlation receiver, which performs iterative decoding to reduce the error and enhance the coding gain. To illustrate this concept, BER performance analysis of rate frac12 orthogonal coding and iterative decoding is presented.
