Statistical methods for radio frequency interference when estimating the performance degradation of digital radio receivers

Abstract

The radiated interference environment can significantly degrade a radio communication system. Since this degradation can give serious consequences, the interference environment needs to be controlled. To foresee the degradation, the interference needs to be quantified and the performance of radio communication systems needs to be analyzed. When estimating the impact from radio frequency interference on digital radio systems, a statistical approach is to prefer. By using the amplitude probability distribution (APD) of an interference source, its impact can be determined. Another successful approach is to use the ordinary Gaussian Approximation (GA) with a correction of the interference power. This concept is based on the impulsiveness correction factor (ICF), which adjust the interference power due to the waveform properies, to avoid serious underestimations of the bit error probability (BEP). These two approaches are suitable methods to achieving accurate performance estimates of a digital radio receiver.
