Noise Immunity of a Mobile Code-Division Multiple-Access Communication System Using an Acoustooptical Noise Spectrum Analyzer

摘要

A model is proposed for estimating the attainable noise immunity and traffic-carrying capacity of wideband code-division multiple-access mobile radio communications systems operating concurrently with narrow-band time-division communications systems in the same frequency band. A possibility is shown of developing controls that monitor parameters of the narrow-band noise with the help of an acoustooptical spec- trum analyzer (AOSA), which provides acceptable speed, frequency resolution, and measurement accuracy.
