Abstract
Aiming at signal detection in α-stable (SαS) noise, a receiver with a new zero-memory nonlinearity limiter (ZMNL) is designed. The proposed ZMNL serves to transform the SαS noise into a standard Gaussian one by using the bi-parameter Cauchy-Gaussian mixture (BCGM) model to approximate the SαS density. Simulation results indicate that the proposed receiver outperforms the conventional sub-optimal receivers for α > 1.5.
