摘要
介绍一种计算分组均衡的OFDM系统的误码率的新方法。该方法可利用付立叶级数展开写出误码率的近似表达式。用该方法分析了采用最小均方根(MMSE)分组均衡器的OFDM系统误码率,实例计算表明,此方法计算量小,精度高。
This paper proposes a new approach fo r error rate evaluation in OFDM syste m with block equalization.The approach can derive an approximate representation of error rate by the Fourier series.The approach is used to calculate the error rate of a block MMSE equalizer i n the OFDM system.Examples show that the approach can enable a mo re precise and efficient calculatio n of error rate performance in the OFDM system.
