“…This section shows that the proposed TMUX can alterna-tively be described in terms of conventional mu ltirate build ing blocks which may be useful in further analysis of the overall system. This is done by utilizing the rational SRC equivalent of the Farrow-based filter [9]. In each b ranch of the TMUX, the A lthough the same analysis methods as for existing TMUXs can be used here, the imp lementation is different.…”

The design of introduces a multi-mode transmulti-plexer (TMUX) structure capable of generating a great set of user-bandwidths and center frequencies. The structure utilizes fixed integer sampling rate conversion (SRC) blocks, Farrow-based variable interpolation and decimation structures, and variable frequency shifters. A main advantage of this TMUX is that it needs only one filter design beforehand. Specifically, the filters in the fixed integer SRC blocks as well as the subfilters of the Farrow structure are designed only once. Then, all possible combinations of bandwidths and center frequencies are obtained by p r o p e r l y a d j u s t i n g t h e variable d e l a y p a r a m e t e r of t h e Farrowbased filters and the variable parameters of the frequency shifters. The paper includes examples for demonstration.It also shows that, using the rational SRC equivalent of the Farrow-based filters, the TMUX can be described in terms of conventional multirate building blocks which may be u sef ul in further analysis of the overall system.

“…Further, ignoring the rational SRCs, it is well known that the transfer function from to is the zeroth polyphase component of the cascaded filter [6]. To make this polyphase component unity, 9 must be an th-band filter. The filters and should thus be designed so that: 1) the zeroth polyphase component of approximates unity and 2) the stopband attenuation of and is high enough.…”

“…It must be noted that, to design the TMUX, there is a need to solve : 1) one filter design problem to get the filter pair and as in (4) and 2) two filter design problems to get the subfilters of the Farrow structures in the synthesis and analysis FBs as in (5). Having solved these problems once, it is only the values of the fractional delays and the parameters of the variable frequency shifters that change for every new configuration 9 For causal filters, the polyphase component should be a pure delay. of standards.…”

Abstract-This paper introduces a multimode transmultiplexer (TMUX) structure capable of generating a large set of user-bandwidths and center frequencies. The structure utilizes fixed integer sampling rate conversion (SRC) blocks, Farrow-based variable interpolation and decimation structures, and variable frequency shifters. A main advantage of this TMUX is that it needs only one filter design beforehand. Specifically, the filters in the fixed integer SRC blocks as well as the subfilters of the Farrow structure are designed only once. Then, all possible combinations of bandwidths and center frequencies are obtained by properly adjusting the variable delay parameter of the Farrow-based filters and the variable parameters of the frequency shifters. The paper includes examples for demonstration. It also shows that, using the rational SRC equivalent of the Farrow-based filters, the TMUX can be described in terms of conventional multirate building blocks which may be useful in further analysis of the overall system.
