摘要

利用导频/数据组合信道估计方案分析了上行双速率DS/CDMA系统的性能。我们的分析允许调查受不同QoS要求影响的最优功率分配的特征，此外，量化在导频/数据组合信道估计方案下系统容量方面的相应优势。我们证明，当具有不同信道配置和服务质量(QoS)要求的不同类别用户共存时，与使用传统基于导频的方案相比，使用导频/数据组合方案可以显着提高系统容量。

Performance of pilot/data-combined channel estimation and power allocations for dual-rate DS/CDMA system over mobile radio channels

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.
