摘要: 该文提出了一族新Bussgang类盲均衡算法统一形式的代价函数，该代价函数具有明确的数学意义，包括了经典的Decision-Directed算法，Sato算法，CMA算法及其变种。根据该代价函数，可以设计出新类型的Bussgang盲均衡算法，该文据此设计了两种新型的Bussgang盲均衡算法，仿真实验验证了这两种新算法的收敛性能。Abstract: This paper introduces a new family of cost function for blind equalization. This cost function family has clear mathematic meanings. This cost function includes the well-know Decision-Directed algorithm, Sato algorithm, CMA algorithm and its mutations. And new Bussgang method can be got by this cost function. This paper presents two new method originated from this cost function. Simulation results verify these two methods convergence.
