The performance of a multicarrier direct sequence code division multiple access (MC-DS-CDMA) system in the generalized Nakagami-m multipath fading channel is studied. A RAKE receiver is deployed for each subcarrier to provide path diversity with maximum ratio combining, MRC, applied. A closed form numerical integration is derived for the bit error rate,(More)
A robust blind multiuser receiver, based on a linearly constrained constant modulus algorithm (LCCMA) with multiple constraints and quadratic inequality (QI) constraint on the weight vector norm, is developed in this paper. Quadratic constraints have been a prevalent approach to improve the robustness against mismatch and modeling errors, uncertainties in(More)
A new low-computational complexity robust adaptive blind multiuser receiver based on a constrained optimization approach with multiple constraints and a quadratic inequality (QI) constraint on the weight vector norm is developed. A diagonal loading technique is required to apply the quadratic constraint where the diagonal loading value is adjusted to(More)
