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。
A new method of calculating the bit error rate of OFDM systems with packet equalization is introduced. This method uses Fourier series expansion to write an approximate expression of bit error rate. The bit error rate of OFDM system using MMSE packet equalizer is analyzed by this method. The calculation example shows that this method has low computational complexity and high precision.
