Abstract :
The implementation of a fast Hadamard transform that operates in the ring of p elements is described with particular applications in an adaptive sequency-division multiplexer. Maximum hardware efficiency is obtained if p is of the form 2r ¿ 1 for any r, and the data to be multiplexed are codcd in 1s-complement arithmetic. The advantage of transforming in a finite ring is that no extra bits are required to store the data as for real-number transforms.
