Title:
【発明の名称】信号端子と無線周波チャネルとの間で信号を多重化するための方法および手段
Document Type and Number:
Japanese Patent JPH08502868
Kind Code:
A
Abstract:
A method and apparatus are provided of transmultiplexing a plurality of signals between a plurality of signal terminals (17 or 29) and a plurality of selected radio frequency channels. The method includes the step of, and apparatus for, frequency translating and filtering the plurality signals between the plurality of selected channels and a polyphase discrete Fourier transform filter bank (16 or 21) within a comb filter (15 or 22). The method further includes the step of frequency division multiplexing the plurality of signals between the plurality of signal terminals and comb filter (15 or 22) within a polyphase discrete Fourier transform filter bank (16 or 21).
