A fast algorithm for binary soft-input-soft-output orthogonal demodulation using symmetry of discrete Walsh functions

Keywords:

A.A. Mahmudov


The fast algorithm for soft binary orthogonal demodulation based on the symmetries of discrete Walsh functions are developed. Achieved a reduction in the complexity of soft binary orthogonal Walsh demodulation used for error-correcting coding.
