Abstract :
A performance analysis is outlined of a star-connected direct-sequence spread-spectrum slotted code-division multiple-access (CDMA) system with differential phase shift keying modulation in an indoor radio environment characterized by Rician fading. The performance is analyzed in terms of the throughput, delay, and stability of the CDMA network. The traffic load is described by a discrete time Markov chain model for a finite number of simultaneous users. Two types of diversity, namely selection diversity and maximal ratio combining, are used to combat multipath fading. Also, the influence of forward error correcting coding on the performance parameters is investigated
