In the application of the non-sinusoidal orthogonal modulation system based on PSWF(prolate spheroidal wave function)in time domain it is difficult to generate PSWF in real-time and complex to realize the non-sinusoidal orthogonal modulation system.Therefore,starting from the Fourier series expansion of PSWF,the relationships between the expansion coefficients and the energy and orthogonality of PSWFs were analyzed.Then,a modulation method based on the inverse discrete Fourier transform(IDFT)and a demodulation method based on the discrete Fourier transform(DFT)were deduced.After that,structures of the modulator and demodulator based on the(inverse)fast Fourier transform(FFT IFFT)were given.As the idea of Fourier transform was introduced to the realization of non-sinusoidal communication system,the connection between non-sinusoidal communication system and(inverse)discrete Fourier transform was established.This method may provide reference for the study of non-sinusoidal technology.
