Abstract

Aiming at the problem of mutual coupling of an encoder and a modulator in wireless data and energy simultaneous transmission (SWIPT), the invention discloses an analysis method of unary coded modulation symbol probability for wireless data and energy simultaneous transmission. The method comprises the steps of: using an encoder and a modulator which are controlled by unary encoding for transmitting information under a Rayleigh channel; constructing a Markov state machine for the unary code, and analyzing a state transition process of the unary code; analyzing a symbol probability expression under any certain modulation mode (M-QAM) condition; and verifying the theoretical analysis by adopting Monte Carlo simulation.

Description

technical field [0001] The invention belongs to the technical field of coding and modulation for simultaneous transmission of wireless digital energy, and in particular relates to a method for analyzing symbol probability of unary coding and modulation for simultaneous transmission of wireless digital energy. Background technique [0002] In recent years, wireless communication has developed rapidly, and researches on wireless communication have emerged in endlessly. In the coming era of the Internet of Things, a novel communication method such as wireless data transmission (SWIPT) will provide energy for low-power devices powered by batteries or supercapacitors on the basis of traditional wireless communication. [0003] At present, there are many coding designs for SWIPT. For example, some code designs are discussed in "Nonlinear code design for joint energy and information transfer", "Constrained codes for joint energy and information transfer" and "Subblock-constrained ...
