Decimation by non-integer factor in software radio receivers
Babić Đorđe, Renfors Markku
The sampling rate conversion is a critical functionality of the software radio receiver. Because the signals of different system standards have incommensurate symbol/sampling rates and a common Analog-to Digital Converter (ADC) is to be used for all supported standards, the decimation factor may become very difficult non-integer number. This paper gives overviews and comparisons of two efficient fractional decimator structures based on Cascaded Integrator-Comb (CIC) filters and low order polynomialbased interpolation filters.
