Adaptive filtering using the fast Walsh-Hadamard transformation

- Summary
- Metrics

Abstract

A fast implementation of the least-mean-square error (LMS) adaptive transversal filter is proposed. The fast Walsh-Hadamard transform technique is adopted in this implementation. This filter is shown to promise a significant reduction in computation over both the conventional time-domain and the frequency-domain LMS adaptive filters. >
