Abstract
This paper describes the performance analysis of a direct-sequence (DS) code-division multiple-access (CDMA) personal communication system (PCS) sharing a common spectrum with narrowband microwave radio links. Spatial and temporal processing are combined to improve the performance of the DS-CDMA system subject to narrowband interference. Degrees of freedom (DOF) provided by space-time (ST) optimum combining schemes are exploited to combat both fading and interference. The performance of several space-time receiver architectures is evaluated in terms of average bit error rate (BER) and it is investigated how this performance is influenced by various parameters.Keywords
