载波干涉OFDM系统的辨析

Analysis of Carrier Interferometry OFDM

将载波干涉码引入OFDM系统,可以提高误码性能,并消除峰均功率比问题。该文从数学角度证明了载波干涉OFDM系统与现有的单载波频域均衡系统其实等同。

Carrier Interferometry （CI） codes may be introduced to Orthogonal Frequency Division Multiplexing （OFDM） systems to improve BER performance and to eliminate the Peak-to-Average Power Ratio （PAPR） problem. This paper demonstrates mathematically that CI/OFDM system is identical to existing Single Carrier transmission with Frequency Domain Equalization （SC/FDE）.
