New constant modulus algorithm suitable for nonconstant modulus signals
Tian Wei · Journal of Communications · 2011
The steady-state mean square error(MSE) of constant modulus algorithm(CMA) can not converge to zero for nonconstant modulus signals.By changing the multimodulus of nonconstant modulus source to single modulus,a new cost function was defined.And the new CMA based on such cost function can lead the steady-state MSE to zero.Theoretic analysis and computer simulation results demonstrate that the proposed algorithm offer high performance.
