Abstract

In this paper, we analyze the performance of uplink dual-rate DS/CDMA system using the pilot/data-combined channel estimation scheme. Our analysis allows for investigating the characteristics of optimal power allocation subject to varying QoS requirements and furthermore, quantifying the corresponding advantage in terms of the system capacity under the pilot/data-combined channel estimation scheme. We demonstrate that, when the different classes of users with varying channel configurations and quality-of-service (QoS) requirements are co-existing, the system capacity can be significantly improved with the pilot/data-combined scheme as compared with that of system using the conventional pilot-based scheme.
