A linearly constrained constant modulus approach to blind adaptive multiuser interference suppression
Joaquı́n Mı́guez, Luis Castedo · IEEE Communications Letters · 1998
This article presents a linearly constrained constant modulus approach for the blind suppression of multiuser interferences in direct-sequence code division multiple access systems. The method performs the same as minimum mean square error receivers and outperforms existing blind approaches because it only requires a rough estimate of the desired user code and timing.
