摘要

在时变频率选择性衰落信道下

针对叠加训练序列的正交频分复用系统

在接收端利用训练序列的一阶统计特性进行信道估计

给出了优化的训练序列分离因子.计算机仿真结果验证了理论分析的有效性.

Abstract

The bit error rate(BER) perfomance of orthogonal frequency-division multiplexing(OFDM) system with superimposed sequence is presented in time varying mufti-path fading channel

which uses the first order statistics of the superimposed sequence.Based on the minimum error rate principle

the optimum sequence separation parameter is given.Finally

the computer simulotion results validate the analysis.
