| 摘 要： | 利用小波提升理论构造一种新的多载波(OFDM)系统,在原傅里叶变换的OFDM(FFT-OFDM)系统的优越性的基础上,扩大系统容量及有效地利用系统的带宽,并使整个系统简单化.进一步对小波提升变换OFDM及傅里叶变换OFDM的抗脉冲干扰性能进行了深入研究,仿真与实验结果表明:基于小波提升的OFDM系统抗脉冲干扰特性远远优于传统OFDM系统.

| Abstract: | A novel OFDM system based on wavelet lifting theory was presented, which inherit the advantages of common OFDM but also conquer some of the disadvantages and simplified the OFDM system. A perfect mathematic model and a computer simulation system were setup in order to study the anti-impulse interference character of the lifting-wavelet-based OFDM and the Fourier-based OFDM. The simulation resolutions show that the performance of the wavelet-lifting-based OFDM is better than Fourier-based OFDM. |
