A modified constrained constant modulus approach to blind adaptive multiuser detection.

A modified constrained constant modulus approach to blind adaptive multiuser detection.

An alternative blind adaptive multiuser detection is investigated based on modified constrained constant modulus (CM) criterion. It is shown that the performance of a CM-based receiver is limited by the received power of the desired user. In this paper, we show that the limitation can be avoided usi...
