무선 OFDM 시스템에서 MUSIC을 기반으로 하는 효율적인 주파수 옵셋 추정
A Novel Scheme based on MUSIC for Efficient Frequency-Offset Estimation in Wireless OFDM Systems

초록
As OFDM-based systems exhibits robustness over wireless channel, it is possible to consider them the next generation of the wireless communications including the mobile communications. However, there is a critical point that OFDM-based systems can receive the distorted signal due to the frequency-offset. Therefore, it is necessary to accurately estimate the frequency-offset for OFDM-based systems to be adopted as the next wireless communication systems. In this paper, the efficient frequency-offset estimation scheme based on MUSIC is presented in 802,1la WLAN systems. As shown in the simulation result, this scheme can improve and optimize the estimation performance.
