Title
Spectral Efficiency Of Direct-Sequence Code-Division Multiple-Access In Cellular Mobile Radio
Abstract
In this paper, the spectral efficiency achieved by a direct-sequence code-division multiple-access (DS-CDMA) system operating in a cellular mobile radio environment is discussed. In contrast to previous works, here, spectral efficiency is examined in terms of channel capacity per user, estimated in an average sense, and the system's inherent diversity potential is considered. The analysis covers only the forward link, assuming a static model of operation for the considered DS-CDMA system. In addition, it is shown that the application of a power control scheme leads to spectral efficiency enhancement due to cochannel interference reduction. Hence, the derived expressions provide a means for quantitative evaluation of cellular DS-CDMA spectral efficiency with respect to multiple-access and cochannel interference.
