In this paper, IIR polyphase filters present several interesting properties: they require a very small number of multipliers to implement, they are inherently stable and have low round off noise sensitivity and no limit cycles. Furthermore, it is possible to achieve almost linear phase designs. Pulse shaping filters have been designed and implemented by using raised cosine filter, Nyquist filter and optimized half band filters for SoftWare Defined Radio (SWDR) based wireless applications. However, IIR polyphase filters enjoy most of the advantages that FIR filters have and require a very small number of multipliers to implement.
