Abstract

Abstract:

Based on the maximum a posteriori probability criterion, performance of a parallel nonlinear detector is compared with that of the optimal parallel linear detector for detection of multiple signals in generalized Gaussian noise. Performance of the parallel nonlinear detector is close to that of the optimal parallel linear detector in Gaussian noise. For generalized Gaussian noise, however, the parallel nonlinear detector has better performance, especially when the noise values are concentrated around zero.

Key words: detection of multiple signals, generalized Gaussian noise, linear detector, nonlinear detector
