Abstract : The results of an investigation and analysis of adjacent channel interference effects, and documentation of the programming of mathematical models which were generated to describe these effects are presented within this report. Provided with each program description is a detailed flow chart illustrating the logic employed within the computer program and a theoretical presentation defining each mathematical model. Required input data is defined and a discussion of the methods used in generating a magnetic tape data base is presented. During the course of the contract, a large amount of measured data was obtained for the purpose of aiding the generation of the mathematical models and in validating the models. The results of these tests and a description of the measurement procedures utilized are presented within this report. Finally a set of appendices is included which contains a treatise on the interdependence of adjacent channel interference effects as related to a common parameter, and provides the program user with computer operating instructions, sample problems, and a complete FORTRAN program listing.
