Nonlinear System Modeling and Analysis with Applications to Communications Receivers
Abstract
The objective was to develop reliable, realistic, and useful mathematical models of communication receivers that must operate in the presence of interfering signals. Major emphasis was placed upon understanding basic pehnomena and developing techniques needed to provide a capability of modeling receiver structures for multi-signal inputs. During the study considerable effort was placed upon modeling so that the effects of co-channel and adjacent channel interfering signals having arbitrary modulations in the presence of receiver nonlinearities might be effectively investigated. Therefore, methods of investigating quasi-linear systems having significant frequency selectivity were developed. Matters relating to intermodulation and crossmodulation distortion as well as gain compression, desensitization, and dynamic range were of primary concern. Associated with these developments was a companion effort to develop effective computer programs that will permit efficient practical application of the basic material presented in this work.
