Abstract

A variable loading recursive least squares (VLRLS) multiuser detection based on the generalized sidelobe canceller is presented to realize the suppression of multiple access interference in code division multiple access (CDMA) systems. In conjunction with a subweight partition approach, the VLRLS detector demonstrates the advantages of insensitivity to dynamic estimate modeling error, less computational load, and more robust to against spreading code mismatches compared to the conventional VLRLS and RLS-based detectors. Simulation results illustrate the effectiveness of the proposed detector.
