摘要 本文分析了基于正交幅度调制的小波包调制在不同信道模型下的性能 ,并对这种小波包多载波调制系统进行了性能仿真 .通过与基于离散傅里叶变换的正交频分复用调制系统进行比较 。 The performance of wavelet packet modulation based on Quadrature Amplitude Modulation under different channel models is theoretically analyzed in this paper,and we simulate the wavelet packet multi carrier modulation system,which is compared with OFDM orthogonal freqaency division multiplexing modulation system based on DFT from variant aspects.Finally,the possibility of wavelet packet modulation application in Digital AM transmission system is discussed.
