为解决短波通信中非合作接收数据短、直接均衡迭代难于收敛的问题,将数据重用的思想引入盲均衡算法中,通过分析数据重用均衡后序列与原始码元序列峰度的关系,验证数据重用方法的有效收敛性,将此方法用于典型Bussgang类盲均衡算法,并分析影响数据重用盲均衡效果的几个因素,通过仿真实验表明,数据重用方法大大减少Bussgang类盲均衡算法收敛所需要的码元数目,有一定的工程实用价值。 In order to solve the problem of short convergence and shortcoming of direct equalization iteration in shortwave communication, the idea of ​​data reuse is introduced into the blind equalization algorithm. The relationship between the data reuse equalization sequence and the original symbol sequence kurtosis is analyzed to validate the data reuse This method is applied to the typical Bussgang-type blind equalization algorithm, and several factors that affect the blind-equalization effect of data reuse are analyzed. The simulation results show that the data reuse method can significantly reduce the number of Bussgang-like blind equalization algorithms required for convergence The number of symbols, there is a certain practical value of the project.
