摘要：本文提出了一種新的基于二階統計量的盲信道辨識與均衡方法。通過對接收信號過采樣，等效的信道矩陣有特殊的結構可以提供足夠的信道信息給我們來估計信道矩陣。根據Tong等人的觀點，本文給出了另外一種證明的方法，并由此得到了一種新的基于二階統計量的盲信道辨識與均衡方法。仿真結果表明此方法和Tong的方法具有同樣的均衡效果。

Abstract: This paper presented a new approach to blind channel estimation and equalization based on Second Order Statistics(SOS). Due to oversampling, the equivalent channel matrix possesses a particular structure which making estimating the channel possible. According to Tong’s point, this text gave another kind of proving method and got a kind of approaches to blind channel estimation and equalization based on Second Order Statistics. Simulation example was provided to demonstrate the algorithm as good as Tong’s techniques.
Key words: SOS；Blind channel estimation；Equalization；Oversampling
