摘要 设计了一种OFDM系统中的时域均衡器,采用前导序列作为时域均衡器的训练序列,系统不需要再额外使用训练序列,在一定程度上降低了系统的开销.计算机仿真结果表明,这种OFDM时域均衡器的性能优于线性均衡器和判决反馈均衡器. In this paper a time-domain equalizer （TEQ） in an OFDM system is designed. With preamble sequences as the training sequences of TEQ, it is no longer necessary to use additional training sequences in the system. Therefore overhead of the system is reduced. Simulation results show that the performance of the TEQ is better than linear equalizer （LE） and decision feedback equalizer.
