Correlation-constrained CMA adaptive array using cyclostationary signal properties

Subband CMA adaptive arrays in multipath fading environment

“…To avoid such a result, various information, such as the unique user codes [15], and the different cyclic correlation property of the users [16], can be used to identify the users and to ensure that the CMA adaptive array catches the desired signal. Such information is usually contained to maintain normal communications and is not necessary to be embodied specially for adaptive control purpose.…”
