Abstract
- Abstract: In the context of sample rate conversion (SRC) filter design; this paper makes two key contributions. Firstly, a practical factorization algorithm has been formulated that iteratively assigns rate change factors to filtering stages of a proposed multi-standard SRC architecture. This multi-stage architecture is composed of multiplexed CIC filters, Farrow interpolators and half-band filters. Secondly, a novel frequency domain technique for joint CIC compensation filter and Farrow interpolator design has been proposed. Based on these contributions; a programmable and computationally efficient SRC filter design scheme with utilization in the digital IF stage of a software radio has been derived. The proposed ideas are explained using design examples and simulation results with parameters corresponding to various commercial wireless communications standards including GSM, IS-95, UMTS and the emerging WiMax IEEE 802.16 standard.
