Abstract

The invention relates to the field of signal transmission, and particularly relates to an N-ary based digital signal transmission method. The N-ary based digital signal transmission method comprises the steps of dividing signals into reference signals and data signals, setting the amplitude range of the data signals to be Fmin-Fmax, transmitting the reference signals according to preset fixed frequency and preset fixed amplitude FA, wherein the fixed amplitude FA=Fmin+(Fmax-Fmin ) / N+Epsilon, and the Epsilon is greater than or equal to 0 and less than or equal to (Fmax-Fmin) / N; and transmitting the data signals according to the same frequency as the reference signals, wherein the amplitude of the data signals is set to be Fn=FA+(n-1)[(Fmax-Fmin) / N]+delta according to a number n to be transmitted at the same time, the n is greater than or equal to 0 and less than N, the N is a natural number which is greater than 2, the delta is greater than or equal to 0 and less than or equal to (Fmax-Fmin) / N, and the FA does not equal to 0. The transmission efficiency of the method provided by the invention on a transmission line is a plurality of times of the transmission efficiency of a binary system, thereby greatly improving the signal transmission efficiency. Meanwhile, the signals are extracted by adopting a differential mode, the signal to noise ratio in the signal transmission process is improved, the anti-interference ability is improved, and various transmitting modes such that the reference signals and the data signals are transmitted synchronously, at intervals and the like can be adopted selectively in the transmission process.

Description

technical field [0001] The invention relates to the field of signal transmission, in particular to a method for digital signal transmission based on N-ary system. Background technique [0002] At present, communication data transmission mostly uses binary, and one bit can only represent one bit of binary. The improvement of transmission efficiency can only use higher transmission frequency, but there is also a limit to the increase of frequency, and the corresponding cost is also increasing rapidly. At present, in order to achieve efficient and high signal-to-noise ratio transmission in the field of communication, amplitude modulation, frequency modulation, and phase modulation are widely used for signal modulation, and most of them still use binary mode for transmission. Modulation frequency and demodulation frequency depend on hardware, and the difficulty of realizing too high modulation and demodulation frequency also increases greatly. In the field of wireless communica...
