| 摘 要： | 分析了若干独立非负随机变量调和平均值的概率密度函数在零点附近的变化特性.在此基础上,分析了单载波分块传输系统中采用频域迫零均衡时的误符号率性能,给出了高信噪比时采用MPSK调制和MQAM调制时的误符号率的闭合表达式,并通过计算机仿真验证了理论分析结果.理论分析和数值仿真结果表明在瑞利衰落信道下,采用迫零均衡的SCBT系统在高信噪比时的平均误符号率与信道多径数目无关. |
| 关 键 词： | 循环前缀 单载波分块传输 迫零均衡 调和平均值 |

| Abstract: | The behavior of the probability distribution function (PDF) of the harmonic mean of several independent non-negative random variables at the origin was analyzed. This result was then applied to study the symbol-error-rate (SER) performance of single carrier block transmission (SCBT) systems with zero-forcing equalization. Closed-form expressions for the SER of SCBT system with MPSK and MQAM modulation in the high SNR region were derived. Simulations were carried out to validate the analytical results. Both ... |
| Keywords: | cyclic prefix single carrier block transmission zero-forcing equalization harmonic mean |
