The application of Walsh transform for forward error correction
Farokh Marvasti, M. Hung, Mohammad Reza Nakhai · 1999
We present a novel class of forward error correcting codes constructed using the discrete Walsh transform. They are a class of double-error correcting codes defined on the field of real numbers. An iterative decoding algorithm for Walsh transform codes is developed and implemented. The error correcting performance of Walsh transform codes over an AWGN channel is evaluated. Selected Walsh transform code parameters are compared to those of the well-known BCH and RS codes.
