Abstract

The invention discloses a wireless data and energy integrated encoding method based on the battery state of a receiver. The method includes using a unary encoding method to perform data energy transmission under a discrete symmetric channel, calculating mutual information between a source and a destination, and calculating The overflow probability and underflow probability of the battery are used to construct a unary coding codeword optimization model, and the genetic algorithm is used to solve the optimal codeword distribution. Based on the unary encoding method, the present invention finds the corresponding optimal codeword distribution by considering the limited battery capacity, meets the requirements of mutual information, and at the same time minimizes the probability of battery energy shortage / battery energy overflow, and satisfies the energy acquisition requirements of the receiver Under the premise of maximizing the average mutual information of the symmetric channel, the integrated coding optimization of wireless data and energy is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless digital energy transmission, and in particular relates to a wireless data and energy integrated encoding method based on the battery state of a receiver and a wireless digital energy simultaneous transmission system. Background technique [0002] In the coming Internet of Things (IoT) era, throughput will be a major part of the study for mass-deployed low-power devices. All these IoT device functions such as data collection, data processing, data download and data upload need to be powered by embedded batteries. Frequent operation may quickly drain the limited battery power. In addition, many IoT devices are deployed in hard-to-reach places, and changing batteries or even replacing IoT devices is a tedious task for network operators, which can significantly increase their operating expenses. As a result, network operators are constantly looking for an economical way to charge IoT devices. Some...
