The Impact of Combined Equalization on the Performance of MC-CDMA Systems

In this work the performance of a combined equalization for Multi-Carrier Code Division Multiple Access (MC-CDMA) systems is analytically evaluated. Combined equalization consists in performing both pre-equalization at the transmitter and post-equalization at the receiver in order to counteract fading and multi user interference. In this paper the authors consider partial combining (PC) at the transmitter and Threshold Orthogonality Restoring Combining (TORC) at the receiver in the downlink of a MC-CDMA system affected by fading.
