Time-variant Cic-filters for Sample Rate Conversion with Arbitrary Rational Factors
Sample rate conversion (SRC) with rational factors can be realized by interpolation followed by decimation, where CIC-Filters [1] can be chosen for either. However, the necessary increase of the sample rate that goes with the interpolation is not feasible in most RF-applications. Therefore a time-variant implementation of CIC-filters is presented which circumvents the high intermediate sample r...
متن کاملFPGA Implementation of Optimized CIC Filter for Sample Rate Conversion in Software Radio Receiver
A software radio receiver is one which is tuned to receive a transmitted signal on multiple communication standards through software rather than hardware. To incorporate multi-standard radio communications an intermediate frequency of high ranges is used. Such high intermediate frequencies when sampled with Nyquist rate gets oversampled due to the phenomenon of Band Pass sampling depending on t...
متن کاملSampling Rate Conversion for Arbitrary Ratio Using Transposed Linear Interpolation and Cic Filter
1. INTRODUCTION In multistandard receivers, the hardware should be configurable or programmable for the reception of different types of signals having different symbol rates. After the AD conversion, utilizing commonly the delta-sigma AD-conversion principle and high oversampling ratio, the sampling rate is reduced to be a low integer multiple of the symbol rate. In this decimation, the desired...
متن کاملDesign of Modified Three Stage Sharpened CIC Filter for Decimation
This paper presents the design of Sharpened three stage CIC filter for decimation. The proposed decimation filter has Cascaded-Integrator Comb filter as first stage, Sharpened Cascaded-Integrator Comb filter as second and third stage. The CIC filter at first stage operates at input sampling rate, sharpened second stage operates at lower rate as compared to first stage and sharpened third stage ...
متن کاملSample Rate Conversion for Software
Software radio terminals must be able to process many various communications standards. These standards are generally based on different master clock rates and thus employ different bit/chip rates. The most obvious solution to cope with the diversity of master clock rates in one terminal is to provide a dedicated master clock for each standard of operation. Not only too costly, this kind of sol...
