摘要：本文提出了一种新的基于二阶统计量的盲信道辨识与均衡方法。通过对接收信号过采样，等效的信道矩阵有特殊的结构可以提供足够的信道信息给我们来估计信道矩阵。根据Tong等人的观点，本文给出了另外一种证明的方法，并由此得到了一种新的基于二阶统计量的盲信道辨识与均衡方法。仿真结果表明此方法和Tong的方法具有同样的均衡效果。

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.
