This work presents blind constrained adaptive filtering algorithms based on the set-membership concept and incorporates time varying bounds for CDMA interference suppression.. Constrained constant modulus (CCM) and constrained minimum variance (CMV) gradient type algorithms designed in accordance with the specifications of the set-membership filtering concept are proposed. Furthermore, the important issue of bound specification is addressed in a new framework that takes into account parameter estimation dependency and multi-access (MAI) and inter-symbol interference (ISI) for multiuser communications. Simulations show that the new algorithms are capable of outperforming previously reported techniques with a smaller number of parameter updates and a reduced risk of overbounding or underbounding.
