摘要 用FFT实现OFDM调制解调,有效地提高了OFDM调制解调速度,但是各子信道之间存在着较大的频谱重叠,导致了子信道之间的功率泄漏,从而引起了严重的串扰.利用小波变换实现OFDM的调制解调可以较好地解决这一问题. Fast Fourier Transform (FFT) is applied to realize the modulation and demodulation of orthogonal frequency division multiplex (OFDM). The method can effectively raise the speed of modulation and demodulation. But each subchannel of compartment is in existence of major spectra overlap, which results in power leakage between subchannels of compartment, and thereby causes severe interference. Using wavelet transform to realize OFDM modulation and demodulation can solve the problem.
