正交频分复用是用于第四代（4G）宽带多媒体无线通信系统的流行调制技术。然而，对于实际通信，子载波之间的正交性可能受到载波频率偏移的影响，导致载波间干扰（ICI），这与归一化多普勒频率成比例地增加了不可减少的误差平层。双径传输方法如共轭抵消和相位旋转共轭抵消（PRCC）以降低带宽效率为代价来抑制ICI。本文研究并提出了一种新的PRCC方案，该方案将传输信号的奇、偶序列分离到两条独立的路径上，以进一步抑制频率选择性衰落信道中的ICI。仿真结果表明，与传统的PRCC方法相比，该方法不仅可以获得更高的数据传输效率，而且在误码率方面也有更好的表现。
Orthogonal frequency division multiplexing is a popular modulation technique for fourth-generation (4G) broadband multimedia wireless communication systems. However, for practical communications, the orthogonality between subcarriers may suffer from carrier frequency offset, resulting in intercarrier interference (ICI), which increases an irreducible error floor in proportion to the normalized Doppler frequency. The two-path transmission methods such as conjugate cancellation and phase rotated conjugate cancellation (PRCC) suppress ICI at the cost of reducing bandwidth efficiency. In this paper, a novel PRCC scheme with the method of separating the odd and even sequences of the transmission signals into two independent paths is studied and proposed to further mitigate the ICI over frequency-selective fading channels. Comparing with the conventional PRCC method, the proposed scheme can not only achieve higher data transmission efficiency, but also provide a better performance on bit error rate according to the final simulation results.
