Comparation and simulation of several blind equalization algorithms
Hong Li · Electronic Design Engineering · 2012
Several blind equalization algorithms are introduced based on the rising blind equalization technology.The high-order QAM signal is choosed as the input signal in this paper,according to the drawbacks of the Constant Modulus Algorithm.Multi-Modulus Algorithm and weighted Multi-Modulus Algorithm.Finally the weighted Multi-Modulus Algorithm with momentum,which has superior performance,is introuduced.Through the computer simulation experiments,we compare the several algorithms in turn for the first time and get some inclusions,weighted Multi-Modulus Algorithm with momentum is better than the other algorithms in performance,it has the faster convergence speed and smaller steady-state error,so it has practical value.
