Throughput and Error State Performance of AMC Scheme in 3G Wireless Systems
In this paper, adaptive modulation and coding technique for OFDM is proposed. In this technique it is possible to switch the modulation order and coding rate in order to better match the channel conditions. The use of adaptive modulation allows higher throughputs and covering long distances. The aim of this paper is to increase the transmission data rate which the high order modulation scheme with low coding redundancy is used. Numerical results are presented showing that the better performance both in terms of error probability and data throughput.
