摘要

我们分析了硬切换算法在1xEV-DO Rev. A系统中的性能。提出了一种计算缝隙误差概率的理论方法。该方法使我们能够评估滤波、迟滞以及系统引入的切换执行延迟的影响。与以往的工作不同，所使用的模型考虑了多个基站(BS)，并考虑了影响从不同基站接收到的不同信号功率的阴影衰落的相关性。理论结果在实际参数范围内得到验证，并通过仿真来评估包错误率(PER)和切换次数。

Performance of Hard Handoff in 1xEV-DO REV A. Systems with the Presence of Rayleigh and Correlated Lognormal Components

We analyze the performance of the hard handoff algorithm used in the 1xEV-DO Rev. A systems. A theoretical approach is presented to calculate the slot error probability (SEP). The approach enables us to evaluate the effects of filtering, hysteresis as well as the system introduced delay of handoff execution. Unlike previous work the model used considers multiple base stations (BS) and accounts for correlation of shadow fading affecting different signal powers received from different BS's. The theoretical results are verified over ranges of parameters of practical interest using simulations which are also used to evaluate the packet error rate (PER) and the number of handoffs.
