Realization of Fast Walsh Transform by using a micro-computer

마이크로 컴퓨터에 의한 Fast Walsh Transform에 관한 연구

In resent years, aided by the power and capability of digital computation, the techniques of Walsh Transform have been exploited for applications in commun- ication and signal processing. This paper presents an approach of FWT by using a 16- bit word-length micro- computer. This FWT implements an in-placed decimation-in-sequency algorithm which improves processing speed and memory storage. Several examples illustrate the process and demonstrate the power spectrum of FWT and that of FFT for the waveforms
