DEVICE AND METHOD FOR COMPENSATION OF DISTORTED SIGNAL IN FIXED BROADBAND WIRELESS ACCESS SYSTEM

摘要

An apparatus for compensating for distortion of a signal in an FBWA(Fixed Broadband Wireless Access) system and a method thereof are provided to reduce complexity of a terminal and to prevent SNR(Signal to Noise Ratio) from being increased by making a base station execute previous equalization. An apparatus for compensating for distortion of a signal in an FBWA(Fixed Broadband Wireless Access) system comprises a coefficient extractor(325), an equalizer(330), and a channel state analyzer(320). The coefficient extractor(325) checks state information of a data input channel according as a terminal, capable of performing wireless access communication, accesses, extracts a signal compensation coefficient value in accordance with the state information of the data input channel, and outputs the extracted compensation coefficient value. The equalizer(330) compensates for distorted signals according to the channel state by using the compensation coefficient value outputted from the coefficient extractor(325). The channel state analyzer(320) analyzes the state information on the data inputting channel.
