Realizing the Modulation and Demodulation of Time-Domain Non-Sinusoidal Orthogonal Signal in HF Channel

A model was set up based on Simulink in this paper,on the conditions of analysis of the model of HF Channel and the principle of the non-sinusoidal time-domain orthogonal modulation and demodulation.A reconstructing method was used for producing PSWF in a small relative bandwidth with getting rid of the limits of the Toeplitz matrix.The Dynamic simulation was realized in the frequency between 3~3.003 MHz.The relations of the BER and the modulation lines were given at last.
