Transmultiplexers — Some new applications

Traditionally, transmultiplexers (TMUX) were deployed in telephone networks (speech transmission) for the TDM ↔ FDM translation, and for on-board processing in satellites. It is known that the theory of multirate filter banks can be applied to TMUX to obtain novel implementations and to gain new insights into their design. Recently, two communications applications, namely, the software radio, and multi-carrier modulation have gained considerable importance. In this paper, we briefly review the multirate DSP framework for TMUX and discuss these two applications using this framework.
