PROBLEM TO BE SOLVED: To provide a multi sub-carrier communication system for providing improved frequency equalization performance and a method thereof. SOLUTION: The multi sub-carrier communication system includes a frequency equalization coefficient calculation unit that receives a reception signal outputted from a frequency equalizer, calculates a new frequency equalization coefficient and periodically updates the frequency equalization coefficient of the frequency equalizer. The multi sub-carrier communication system periodically calculates and updates the frequency equalization coefficient not only during an initialization interval for measuring a channel characteristic but also during a data receiving interval and thus, it is possible to dynamically adapt to changes of the channel characteristic over the passage of time, thereby improving performance of the frequency equalizer. Accordingly, the performance of the multi sub-carrier communication system is enhanced. COPYRIGHT: (C)2006,JPO&NCIPI
