TLDR
A new algorithm is proposed for the digital implementation of the M -channel SSB-frequency-division multiplexing (FDM) modulator and demodulator, which is computationally attractive and inherently insensitive to parameter quantization.Abstract:

A comprehensive survey of digital transmultiplexing methods
H. Scheuermann,Heinz G. Gockler +1 more
TL;DR: The overall performance of the various transmultiplexer approaches are compared with each other by means of different criteria, such as stability under looped conditions, absolute value of the group delay, computational and control complexity, modularity, potential of intelligible crosstalk, and the impact of out-of-band signaling.

Design of a 24-channel transmultiplexer
M. Narasimha,A. Peterson +1 more
TL;DR: The design of a transmultiplexer capable of performing the bilateral conversion between one 1544 kbit/s digital signal and two analog group signals and it is shown that an FIR filter bank required as part of such a trans multiplexer can be realized efficiently by cascading a discrete cosine transform processor and a weighting network.

An Improved Method for Digital SSB-FDM Modulation and Demodulation
R. Maruta,A. Tomozawa +1 more
TL;DR: A new method for digital implementation of SSB-FDM modulation and demodulation is presented, which utilizes the FFT algorithm to reduce the multiplication rate.

FDM/TDM Transmultiplexer
George D. Dill,Atsushi Tomozawa,James R. Fillion,Mian Zaheer Ali,Clyde E. Burwell,Brady Warner,Richard W. Jones +6 more
TL;DR: In this article, a FDM/TDM trans-multiplexer uses sampling rate multiplication to increase the sampling rate for time division multiplexed (TDM) to frequency-division multiplex (FDM) conversion and decrease the sample rate for FDM to TDM conversion.

A generalized scheme for an all-digital time-division multiplex to frequency-division multiplex translator
T. Claasen,W. Mecklenbrauker +1 more
TL;DR: It is shown that existing systems for this translation, e.g., those in which a fast Fourier transform (FFT) processor is used, can be derived from this generalized scheme as special cases.
