Yuichi Kida, Takuro Kida · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2003
The approximation in the maximally distinct or under sampled filter banks is considered. In this discussion, the decimated sampling interval T satisfies T≥M, where M is the number of paths of the filter banks. Moreover, we present the optimum transmultiplexer TR. This result is extended to the design of wireless transmultiplexer, used in CDMA systems, for example.
