An analytical constant modulus algorithm
IEEE Transactions on Signal Processing, 1996 Iterative constant modulus algorithms such as Godard (1980) and CMA have been used to blindly separate a superposition of cochannel constant modulus (CM) signals impinging on an antenna array. These algorithms have certain deficiencies in the context of convergence to local minima and the retrieval of all individual CM signals that are present in the ...

New normalized constant modulus algorithms with relaxation [PDF]
IEEE Signal Processing Letters, 1997 A new normalized constant modulus algorithm is proposed that has a more desirable error performance surface (EPS) than the existing constant modulus blind equalization algorithms. We show that for an autoregressive channel, a well-known class of undesirable local solutions (ULSs) does not exist.

Efficient Algorithms for Constant-Modulus Analog Beamforming [PDF]
IEEE Transactions on Signal Processing, 2022 The use of a large-scale antenna array (LSAA) has become an important characteristic of multi-antenna communication systems to achieve beamforming gains. For example, in millimeter wave (mmWave) systems, an LSAA is employed at the transmitter/receiver end to combat severe propagation losses.

New constant modulus algorithm suitable for nonconstant modulus signals
Tongxin xuebao, 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 ...

Optimization Parameters of Trading System with Constant Modulus of Unit Return
Mathematics, 2020 The unit return is determined as the return in the quotation currency (QCR) per the unit of base exchange medium (BEM). The main purpose is to examine the applicability of a trading system with a constant modulus of unit return (CMUR).
