摘要
针对相干光正交频分复用(CO-OFDM)系统高峰均比(PAPR)的问题,提出一种基于离散余弦变换(DCT)和改进的分段线性压扩(TPWC)变换的方案。介绍了DCT变换和改进的TPWC变换的基本原理,并将两者结合应用到CO-OFDM系统中。
A joint technique is proposed based on the Discrete Cosine Transform (DCT) and modified Two- Piecewise Companding(TPWC) transform to reduce the high Peak-to-Average Power Ratio (PAPR) in Coherent Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) systems. First, the working principle of DCT and modified TPWC was introduced. Then applied them to the CO-OFDM systems.
