Fdm/Tdm Transmultiplexer
View pageUS Patent:
41996607, Apr 22, 1980
Filed:
Nov 7, 1977
Appl. No.:
5/849584

Assignee:
Communications Satellite Corporation - Washington DC
International Classification:
H04J 100
US Classification:
370 50
Abstract:
A FDM/TDM transmultiplexer uses sampling rate multiplication to increase the sampling rate for time division multiplexed (TDM) to frequency division multiplexed (FDM) conversion and decrease the sampling rate for FDM to TDM conversion. The rate multiplication filters are realized digitally in order to exploit the computational advantage of Fast Fourier Transform (FFT) algorithm, and channel filtering is implemented by a single time-shared sixth-order elliptic digital recursive filter. A novel FFT processor and recursive filter are disclosed which may be used in the system.
