摘要:
正交频分复用是一种多载波传输技术,在无线通信应用中有很好的发展前景。但是在OFDM中存在一个比较大的缺点:过高的峰值平均功率比。研究了OFDM系统中PAPR算法中的部分传输序列(Partial Transmit Sequence,PTS)算法及其峰均比的抑制性能,并在其基础上提出一种能够降低传统PTS算法复杂度的m序列PTS算法,并采用MATLAB仿真验证了算法的可行性。提出了在FPGA中实现的峰均比抑制模块设计方案并加以验证,结果证明此设计方案能够很好完成峰均比抑制功能
Abstract:
OFDM is a technique of multicarrier transmission,which has a good prospect in wireless communication.However,OFDM has a disadvantage:large peak-to-average power ratio.This paper mainly focuses on the study of the peak-to-average power ratio of Orthogonal Frequency Division Multiplexing reduction algorithm of partial Transmit Sequence,research PAPR performance,and propose a low-complexity of traditional PAPR using m-sequence PTS approaches,and prove the algorithm workable using MATLAB simulation.The paper proposes a design scheme which will be implemented in FPGA,the results show that the scheme can complete the reduction of peak-to-average power ratio performance perfectly
