Abstract

This paper addresses issues relating to software-defined receivers. Namely radio frequency (RF) to baseband architectures and the signal processing algorithms involved. Several direct conversion receiver architectures are introduced and analyzed for their performance. Issues relating to the quadrature imbalances and DC offset impairments are analyzed and detailed. To estimate and compensate for these impairments, several DSP algorithms are proposed and simulated for use with these receivers.
