Novel non-uniform multi-tone system based on Ramanujan sums

  • 摘要: 针对高速移动通信,多普勒效应和多径效应导致信道非均匀,提出一种基于拉曼努金和的频谱可调的非均匀调制多载波系统.首先,根据拉曼努金和的正交性和周期性,推导了拉曼努金傅里叶正反变换的完全重建条件,进而建立基于拉曼努金和的多载波调制系统(RFMT,Ramanujan Fourier Multi-Tone system).由于拉曼努金和的非均匀频谱分布性质及频率共振性质,RFMT在不同载波通道的误比特率不同,可实现对数据的不均等保护.在非均匀信道下RFMT具有优于OFDM的抗多径能力,仿真验证了RFMT的抗多径有效性.在使用迫零均衡算法时,10-5误比特率下,根据信道情况设计的非均匀多载波系统RFMT对Eb/N0的要求可以比OFDM低4 dB.
