非合作通信中OFDM系统的载频偏移盲估计方法
Blind carrier frequency offset estimation for OFDM in non-cooperative communication
摘要
Abstract
In view of the problem of poor carrier frequency offset estimation performance over multipath channels for orthogonal frequency division multiplexing( OFDM ) systems in non-cooperative communication , a new blind carrier frequency offset(CFO) estimation method is proposed . Firstly , the cost function based on the difference in amplitude is proposed . Secondly , the terminal cost function is derived by the product of the adjacent subcarrier 's amplitude . Finally , the CFO estimation based on the polynomial interpolation is realized by the transformation cost function . Simulations show that the proposed CFO estimation method has a better performance and lower computational complexity over the multipath channels .关键词
