摘要

本文旨在介绍循环前缀(CP)长度对电力线通信(PLC)中使用的多载波调制的最大可实现吞吐量的影响。计算了包括信道脉冲响应长度超过循环前缀长度所引起的干扰在内的最大吞吐量，并与仿真结果进行了比较。最优循环前缀长度的统计分布是使用Orange实验室在不同住宅场地进行的通道测量进行的。统计分析有助于确定接近最佳可实现吞吐量的最佳CP长度配置。

Statistical analysis of the Cyclic Prefix impact on indoor PLC capacity

This paper aims at presenting the impact of the Cyclic Prefix (CP) length on the maximal achievable throughput for multicarrier modulations used in Power Line Communications (PLC). The maximal throughputs including the interference caused by a channel impulse response length exceeding the cyclic prefix length are calculated and compared to simulation results. The statistical distribution of the optimal cyclic prefix length is conducted using channel measurements that were carried out by Orange Labs in different residential sites. Statistical analysis helps determine the best CP lengths configurations that approach the optimal achievable throughputs.
