Effects of densensitization on mobile radio system performance, part I: Qualitative analysis

Abstract

Densensitization, or the blocking of the receiver portion of the communications system, is one of the principal causes limiting receiver operation, especially in mobile networks under cositing situations. A clear understanding of this nonlinear effect is thus essential when attempting to improve the reliability of mobile radio communication systems so as to prevent severe interferences. A thorough qualitative analysis of desensitization effects on receiver parameters is provided and semi-empirical and statistical relationships useful for performing quantitative computations are developed. The developed analysis initially treats the computation of desensitization effects on radio communication system scenarios for both a single interfering transmitter and several simultaneous interfering transmitters. The results of this qualitative analysis then allow us to compute quantitatively the desensitization effects of a typical mobile radio system which are presented in a second paper.
