Query: Blind Adaptive Interference Suppression Based on Set-Membership
  Constrained Constant-Modulus Algorithms with Time-Varying Bounds   This work presents blind constrained constant modulus (CCM) adaptive
algorithms based on the set-membership filtering (SMF) concept and incorporates
dynamic bounds {for interference suppression} applications. We develop
stochastic gradient and recursive least squares type algorithms based on the
CCM design criterion in accordance with the specifications of the SMF concept.
We also propose a blind framework that includes channel and amplitude
estimators that take into account parameter estimation dependency, multiple
access interference (MAI) and inter-symbol interference (ISI) to address the
important issue of bound specification in multiuser communications. A
convergence and tracking analysis of the proposed algorithms is carried out
along with the development of analytical expressions to predict their
performance. Simulations for a number of scenarios of interest with a DS-CDMA
system show that the proposed algorithms outperform previously reported
techniques with a smaller number of parameter updates and a reduced risk of
overbounding or underbounding.
