Evaluation of Link Adaptation Methods in Multi-User OFDM Systems with Imperfect Channel State Information

Abstract

Link adaptation has shown to be a method of improving the wireless communication system throughput over quasi-static fading channels. Link adaptation, however, requires channel quality information (CQI) at the transmitter side, which is difficult to obtain accurately. Within the European WINNER project, a low complexity, near optimum, mutual information… (More)
