部分功率訓(xùn)練序列與OFDM承載數(shù)據(jù)的優(yōu)化分離

Optimum Separation of OFDM Data and Partial Power Training Sequence in Frequency Selective Fading Channels

  • 摘要: 在采用部分功率訓(xùn)練序列同步的OFDM系統(tǒng)中,接收到的OFDM承載的數(shù)據(jù)信號會受到部分功率訓(xùn)練序列的嚴(yán)重干擾。由于信道估計的誤差,使得對訓(xùn)練序列的分離同樣存在誤差。本文給出了在頻率選擇性衰落信道中,一種優(yōu)化的抑制訓(xùn)練序列對OFDM承載數(shù)據(jù)的干擾的方法。通過理論分析,給出了優(yōu)化的訓(xùn)練序列對消因子。計算機(jī)仿真結(jié)果驗證了理論分析的合理性。
