Block Least Mean Square Adaptive Combining for MC-CDMA Systems
Jianhua Ge · Telecommunication Engineering · 2006
This paper proposes a block least mean square adaptive combining scheme for MC-CDMA systems.In Rayleigh slow fading channel,channel noise and MAI(multiple access interference) is canceled to the full extent at the cost of only tens of training symbols.Simulation shows that the downlink performance of block least mean square adaptive combining is close to non-adaptive MMSEC(minimum mean square error combining) in a fully loaded system.Moreover,when the load is small(as measured by number of active users),the adaptive scheme is shown to outperform MMSEC.
