Abstract
Adaptive modulation and coding (AMC), which has a number of variation levels in accordance with the fading channel variation, is a promising technique for communication systems. In this paper, the AMC method for OFDM system with cluster in pursuit of bandwidth efficiency and performance improvement is presented. And the AMC schemes applied into each cluster or some clusters are determined by the minimum or the average SNR value among all subcarriers within the corresponding cluster. It is important to find the optimal information related to cluster because AMC performance can be varied according to the number and position of cluster.
