利用高阶矩解决数字通信中的盲均衡问题
A METHOD OF BLIND EQUALIZATION IN DIGITAL COMMUNICATION USING HIGH-ORDER MOMENTS
【摘要】 针对盲均衡算法中 ,以梯度的估值计算抽头最佳系数时收敛性不理想的问题 ,介绍了一种新的以高阶矩来求解均衡系数的方法 ,并对该方法的性能进行了讨论 .
【Abstract】 Blind equalizer which needs no known training sequence when compensating the channel distortion has been playing an important role in digital communication system. But most blind equalizer converge very slow, a new algorithm for calculating the best coefficients using high order moments presented, and get a conclusion for the performance of the method.
