Abstract: During last two decades, an extensive research has been carried out for the design and development of digital filter banks. These systems operate in two modes, i.e. either in analysis/synthesis mode or synthesis/analysis mode. First case corresponds to filter banks, in which input signal is decomposed into two or more signals. Second case corresponds to transmultiplexer systems, where several signals are transferred through a single channel. Transmultiplexer is a foremost module of multicarrier communication scheme, which is obtained by reversing the role of analysis and synthesis filters in the filter banks. They are often used in channel coding application in communication, and are also referred as a multi-input, multi-output system that uses sampling rate alteration and filtering to combine M signals for transmission across a channel, and then recovers the M input signals. This paper presents a comprehensive overview of transmultiplexer systems: analysis and design techniques of transmultiplexer systems. Finally, some concluding remarks about current and future research in transmultiplexer systems are presented.
