Analysis of the Polyphase Iir Structure in the Constraint Coefficient Space

چکیده
This paper presents two techniques for the design of digital filters with bit-constrained coefficients, the “bit-flipping” algorithm [1] and the Downhill Simplex Method modified to deliver fixedpoint filter coefficients [2]. Both techniques can be applied both to design filters from scratch and to optimise their floating-point equivalents. They are comparatively presented through an example of a number of polyphase [3][4], filters.

Constraint two-path polyphase IIR filter design using downhill simplex algorithm
The paper addresses tlie design of tlie polyphase IIR filters based on the “’-order single-coefficient allpass sub-filters in the constraint coefficient space using the Constraint Dowdiill Simplex Algorithm. Incorporating the bit-flipping algorithm into its core engine allowed the optitilisation routine to converge to better target designs without affecting tlie Iiigli speed of tlie original al...
متن کاملPolyphase IIR filter banks for subband adaptive echo cancellation applications
Polyphase IIR structures are known to be very attractive for very high performance filters that can be designed using very few coefficients. This combined with their reduced sensitivity to coefficient quantization in comparison to standard FIR and IIR structures makes them very applicable to very fast filtering especially when implemented in fixed point arithmetic. In this paper we suggest repl...
متن کاملThe design of arbitrary-band multi-path polyphase IIR filters
The polyphase IIR N-path structure based on the N-order allpasses is very attractive for high quality fractional-band filters, as high attenuation and small passband ripples can be achieved for much less coefficients than other filter structures. However its general form suffers from spikes in the stopband independent from the coefficient values. The paper presents alternative ways to those fou...
متن کاملNew Subband Adaptive IIR Filter Based On Polyphase Decomposition
Abstract—We present a subband adaptive infinite-impulse response (IIR) filtering method, which is based on a polyphase decomposition of IIR filter. Motivated by the fact that the polyphase structure has benefits in terms of convergence rate and stability, we introduce the polyphase decomposition to subband IIR filtering, i.e., in each subband high order IIR filter is decomposed into polyphase I...

The perfect linear phase requirement can be achieved only by direct design with an FIR filter at the expense of high filter order and hence high computational burden for the given specification. Alternatively, IIR filters can be designed with much smaller orders than their FIR counterparts, but at the expense of the nonlinear phase. However, it is possible to design almost linear-phase IIR filt...
