Abstract :
A linearly constrained constant modulus algorithm (CMA) for CDMA detection and equalization is proposed in this paper. Multipath propagation is assumed and only the code sequence of a particular desired user is known. The new algorithm overcomes the shortcoming that the unconstrained CMA cannot lock to the desired user, and yields better performance compared to the existing constrained minimum output energy method
