摘要
在OFDM系统中,子载波间的正交性是保证OFDM性能的重要保障。针对双选择性衰落信道下的OFDM系统,该文在分析载波间干扰(ICI)的基础上,提出了一种采用频域迭代消除ICI的均衡算法。分析和仿真结果表明此方法能有效地保证载波间的正交性和改善了OFDM系统的误码率(BER)性能。
The orthogonality between subcarriers is important to the performance of orthogonal frequency division multiplexing （OFDM） system. This paper proposes a novel equalization method with frequency domain iteration to cancel inter- cartier interference （ICI） of OFDM over doubly - selective fading channel, on the basis of the analysis of ICI. The analysis and simulation results demonstrate the equalization method can keep the orthogonality between inter- carriers effectively and improve the performance of bit error rate（BER） of OFDM system,
