Abstract

Cross correlator systems, analog and clipped input channels, with correlated random narrow band Gaussian noise as inputs are computer simulated. The performance of each system is evaluated on the basis of the output signal-to-noise ratio. The output SNR of each system is compared with theoretical asymptotic approximations computed as a function of the SNR of the input channels. The output of the simulation compares within 3 dB of the asymptotic approximations for the analog correlator for all values of the correlation coefficient tested and for the systems with clipped input channels with uncorrelated inputs. For the systems with clipped input channels, certain combinations of the input SNR with non-zero correlation cause the output SNR to be zero. This causes discontinuities in the dB plot. For the systems with clippers and non-zero correlation of the input channels, the output of the simulation compares within 3 dB of the results of the asymptotic approximations when no discontinuities occur in the output plot.
