Performance study of nonlinearities blind correction in wideband receivers

Abstract

International audienceThis paper studies a post-distortion correction technique applied to a nonlinear receiver. The employed technique relies on the assumption that the input signal is bandlimited and uses the signal spreading in the free energy band in order to perform the estimation. The study focuses on three points: the input distortion level impact, filter complexity and quantization. A good sizing of these key parameters is mandatory in order to have an optimized CMOS implementation
