| 摘 要： | 正交频分复用(OFDM)和MIMO-OFDM技术都存在高峰均比的问题,大多数方法都是把降低OFDM峰均比的方法直接使用MIMO-OFDM系统,但在与MIMO-OFDM系统的匹配上存在较大问题。分析了OFDM和MIMO-OFDM的系统模型及PAPR,从理论上分析了OFDM和MIMO-OFDM两系统的关系,给出了在MIMO-OFDM系统中降低PAPR需要注意的问题,为OFDM和MIMO-OFDM系统的技术实用化做好理论基础。

| Abstract: | The orthogonal frequency division multiplexing(OFDM) and multi-input multi-output orthogonal frequency division multiplexing(MIMO-OFDM) has high peak-to-average power ratio(PAPR).Most of methods is used to reduce PAPR directly by using the OFDM system,but many problems occur in matching with MIMO-OFDM system.This paper respectively analyzes OFDM and MIMO-OFDM system models and PAPR,and the relations between them theoretically.In the paper,we summarize the notices in reducing PAPR in the MIMO-OFDM system,whi... |
