A new hybrid heuristic multiuser detector for DS-CDMA communication systems
In this work, we present a new multiuser detection (MUD) structure which results from incorporating the tabu search (TS) heuristic algorithm with the local search (LS) heuristic algorithm. The new proposed structure brings much improvement when compared to both the conventional (matched filter) detector and the decorrelating detector. Moreover, the new TS-LS-detector proposed here approximates well the performance of the optimal MUD detector but with a very low computational complexity. Copyright (C) 2008 John Wiley & Sons, Ltd.
