摘要

本文提出了一种基于互补序列对的正交频分复用(OFDM)系统的新型包序文。演示了这种方法如何允许接收器动态地在频域均衡(FDE)和时域均衡(TDE)之间进行选择。由于FDE提供了低复杂度的零强迫(ZF)均衡，而TDE易于进行最小均方误差(MMSE)估计，因此得出结论，频谱平坦化互补序列对提供了出色的灵活性和性能组合。

Complementary Channel Estimation and Synchronization for OFDM

In this paper, we present a new type of packet preamble for orthogonal frequency division multiplexing (OFDM) systems that is based on a complementary sequence pair. It is shown how this approach permits a receiver to dynamically choose between frequency-domain equalization (FDE) and time-domain equalization (TDE). With FDE offering a low-complexity zero-forcing (ZF) equalization and TDE facilitating easy minimum mean square error (MMSE) estimation, it is concluded that a spectrally-flattened complementary sequence pair offers an outstanding combination of flexibility and performance.
