A Modified Batch Processing Constant Modulus Algorithm
Kong Yuanyuan · Telecommunication Engineering · 2012
By analysing the shortages of traditional batch processing algorithm,a new batch processing constant modulus algorithm derived by conjugate gradient direction to minimizing the constant modulus criterion(CG-BPCMA) is presented. The new algorithm uses conjugate gradient direction to choose the search direction and the analytical form of conjugate gradient direction is deduced.Simulation results show that in flat Rayleigh fading synchronous channel environment blind equalization system,the new algorithm overcomes the shortcomings of SD-BPCMA and NT-BPCMA effectively,not only has lower complexity,but also can converge to the minima of the constant modulus criterion quickly.
