A blind channel shortening for multiuser, multicarrier CDMA system over multipath fading channel
F. Bouasria, A. Djebbari, M. Chetioui
In this paper we derive the Multicarrier Equalization by Restoration of Redundancy (MERRY) algorithm: A blind, adaptive channel shortening algorithm for updating a Time-domain Equalizer (TEQ) in a system employing MultiCarrier Code Division Multiple Access (MC-CDMA) modulation. We show that the MERRY algorithm applied to the MC-CDMA system converges considerably more rapidly than in the Orthogonal Frequency Division Multiplexing (OFDM) system . Simulations results are provided to demonstrate the performance of the algorithm.
