On the application of variable digital filters (VDF) to the realization of software radio receivers


This paper studies the application and design of variable digital filters (VDF) to realize the sample rate converter (SRC) in a new architecture of software radio receivers. The VDF-based SRC provides variable fractional delay in the passband and additional attenuation in the stopband. The design of the VDF using weighted least squares (WLS) and… (More)
