Electromagnetic System Interaction Algorithms (SEMCA, IPM, TRED, and COSAM are Compared with Respect to Modeling Philosophy, Flexibility, Data Base, Noises and Interferences, Interference Threshold Criteria, Attenuation Modeling and Antenna Coupling, and Printouts).

Abstract : TRED is a system design tool while SEMCA, IPM, and COSAM are mainly used as interference prediction tools. A user-computer interactive program is recommended. It would be based on the TRED design philosophy and would be used during the design stage of shipboard rf communication systems. In addition, a performance evaluation program for shipboard rf communication systems is recommended. The purpose of the evaluation is to predict final system performance in terms of articulation index and bit error rate. (Author)
