The invention discloses a compound signal transmission and communication method based on an equal-amplitude equal-period modulated carrier wave technology, which comprises two parts, including the compound transmission of an analog signal and digital information and compound information receiving demodulation, wherein the compound transmission of the analog signal and the digital information comprises the following steps of coding an information source, coding a channel, forming a carrier wave, modulating a base band and modulating upper frequency conversion; in the carrier wave formation, a wave shape of a carrier wave is directly changed by a binary system information code element; compared with a standard sinusoidal wave, a modulated wave shape f1(t) generated when an information bit is one and a modulated wave shape generated when the information bit is zero have an adjustable tiny difference; and the compound information receiving demodulation comprises the following steps of demodulating lower frequency conversion, the analog signal and the digital information, decoding the channel and decoding the information source. The method realizes the compound transmission of the analog signal and the digital information and improves the utilization ratio of communication and transmission resources.
