Digital Communications in Fading and Jamming-COMLINK Users' Manual
Abstract
Digital communications systems that must operate successfully in the presence of signal propagation disturbances and radio frequency (RF) interference impose design requirements different from those for undisturbed channels. Without special attention, channel disturbances can degrade and possibly completely disrupt a communications link. Fortunately, the effects of RF propagation disturbances and interference, often referred to as signal fading and jamming, can be mitigated by careful design. This includes proper selection of modulation, coding, diversity, carrier tracking, synchronization, and signal acquisition techniques. The COMLNK computer simulation program was developed to facilitate the design of robust communications systems that must operate in adverse signal conditions. COMLNK provides a highly accurate numerical laboratory with which various design options can be quantitatively evaluated prior to commitment to hardware. The program is also useful in evaluation of existing systems, and it has proven to be invaluable in planning and conducting hardware tests. This document outlines the capabilities of the simulation and contains information useful in applying the code to the design, evaluation, and testing of digital communications systems.
