Performance of coherent PSK and DPSK systems in an impulsive and Gaussian noise environment
Abstract
General probability of error expressions for coherent PSK and differentially coherent DPSK systems in the presence of both impulsive and Gaussian noise are derived. The presented impulsive and Gaussian channel disturbance is a first order approximation to operational multichannel satellite and terrestrial microwave systems in which in addition to front-end Gaussian noise, out-of-band intermodulation noise is also present. The analysis contains an extension of the method developed by Bello and Esposito (1969, 1971), to include the Gaussian as well as the impulsive noise environment. The numerical results show that a well-defined threshold region exists above which the effect of the impulsive noise on the system performance is predominant.
