Abstract
Provided are an apparatus and method for generating channel information and apparatus and method for adaptive transmission employing the same. The channel information generation apparatus comprises an estimator for estimating current channel information of a multi-carrier received signal for each path, a short-period channel information generator for predicting channel information after a predetermined minimum transmission delay time based on the current channel information estimated by the estimator to generate short-period channel information, and a long-period channel information generator for deriving statistic information of error between the channel information predicted by the short-period channel information generator and actual channel information at the time of transmission to produce long-period channel information. The invention is applied to mobile communication systems using multi-carrier.
