Co-channel interference modeling of the ANSI/TIA/EIA-95-B code division multiple access cellular system

Spectral efficiency is an essential component of existing and new technologies in personal communications services (PCS). The growing demand for PCS has resulted in an increasingly crowded spectrum. Code division multiple access is one of the best methods for efficient use of the radio spectrum. Code division is used in some second generation PCS systems and is used or proposed for all third generation PCS systems. The capacity of code division cellular systems is limited primarily by interference caused by co-channel interferers and other channel interferers. This paper introduces an interference model of the ANSI/TIA/EIA-95-B cellular system which can be used to study the effects of co-channel interference and presents results of four preliminary simulation scenarios run using the output of the model.
