摘要 把各种常用数字波形的Chen-Mobius逆变换函数族作为各位数字信号的编码波形,直接将它们叠加在一个信道上进行传输.在接收端,用带通滤波器对叠加信号按编码波形族的频谱进行各谐波分频滤波,得出各分频分量.然后,按一定算法重新构成各位编码波形,用与各位编码波形对应的数字信号对其进行相干解调,得出各位的编码信息,实现数字信号的多位并行编码传输,提高传输效率与节省投资. Applying the Chen-Mobius inverse transform function set of some often-used digital waveforms as the coding waveforms of each bit digital signal, they were then added directly together and transmitted on a physical channel. At the receiving end, band-pass filters were used, according to the frequency spectrum of the coding waveforms, to derive each harmonic frequency component. Afterwards according to a certain algorithm, the coding waveforms for each bit were reconstituted and coherently demodulated by corresponding digital signals. The coded information of each bit was derived and the parallel multi-bits coding transmission was realized. The efficiency of the transmission was highly improved and the investment was greatly saved.
