A communication method for simultaneous modulation of pulse width and frequency

Abstract

The invention is to provide a communication method capable of realizing pulse width and frequency simultaneous modulation, which can greatly improve data transmission capacity. The method comprises the following steps: A) sending a subscript Y value in a one-dimensional array M[X], of which the bit width is N (0<N<=8), and the length is X (X>0), to a frequency modulator to generate a frequency pulse signal fY, the period of which is T; B) sending the frequency pulse signal fY and a data array M[Y], the subscript of which is Y (0<=Y<X), to a pulse width modulator, which modulates the data array M[Y] to obtain a frequency pulse width modulation signal P, which is within a 1-99% duty ratio range and the period of which is T; and C) sending the received frequency pulse width modulation signal P to a frequency demodulator and a pulse width demodulator for demodulation. The original 1-bit data modulation and transmission is improved to one or more-byte modulation and transmission, thereby greatly improving data transmission capacity.

Description

technical field [0001] The invention relates to the field of digital signal modulation, in particular to a communication method for simultaneously modulating pulse width and frequency. Background technique [0002] At present, the most common digital signal modulation methods used by people are pulse frequency modulation or pulse phase modulation. These modulation methods use discrete data to modulate the frequency or phase of the signal, and can only transmit or receive 1 bit of data at a time, and it is difficult to transfer the data Increased transmission capacity. Contents of the invention [0003] The object of the present invention is to provide a communication method of pulse width and frequency simultaneous modulation which can improve the data transmission capacity. [0004] The technical solution of the present invention is achieved in this way: a communication method for simultaneously modulating pulse width and frequency, comprising the following steps: [00...
