Reverse-Link Performance of Synchronous Cellular DS-CDMA Networks in Dispersive Rician Multipath Fading Channels
In this paper, the reverse-link performance of synchronous DS-CDMA cellular networks is investigated in Rician multipath fading environments. The system’s performance is evaluated in terms of the achievable average bit error rate (BER) and the user capacities of two different network layouts, namely those of a uniform grid of hexagonal multiple cells and a single isolated cell.

Upon comparing both networks to a conventional asynchronous CDMA system, we demonstrate an achievable user capacity gain of 25% to 56% for synchronous uplink transmission scenario at BER =10-3.

Abstract

In this paper, the reverse-link performance of synchronous DS-CDMA cellular networks is investigated in Rician multipath fading environments. The system’s performance is evaluated in terms of the achievable average bit error rate (BER) and the user capacities of two different network layouts, namely those of a uniform grid of hexagonal multiple cells and a single isolated cell. In the multiple-cell scenario, the impact of the other cells’ interference on the attainable capacity of the synchronous DS-CDMA uplink in investigated. Upon comparing both networks to a conventional asynchronous CDMA system, we demonstrate an achievable user capacity gain of 25% to 56% for synchronous uplink transmission scenario at BER =10-3.
