信道均衡是克服码间干扰的重要措施。但是由于传统的均衡需要发送一训练序列来进行初始抽头系数的调节,这会降低通信中的有效数据传输率。盲均衡技术的提出就是为了解决这一难题。文中从盲均衡的信号模型入手,对Godard算法进行了研究与仿真,并讨论了其中的几个关键参数。 Channel equalization is an important measure to overcome the intersymbol interference. However, since the traditional equalization needs to send a training sequence to adjust the initial tap coefficients, this will reduce the effective data transmission rate in communication. Blind equalization technology is proposed to solve this problem. Starting from the signal model of blind equalization, Godard algorithm is studied and simulated, and some of the key parameters are discussed.
