Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0030] A method for quickly evaluating the probability of interruption of information transmission in wireless power supply communication, characterized in that it includes the following steps:

[0031] 1) MIMO transmits WET, realizes WET through MINO technology: precode PB, and then go through transmitter mapping, MIMO transmission, and receiver mapping in sequence to obtain wireless node energy signals;

[0032] 2) MIMO transmits WIT, realizes WIT through MINO technology: MIMO is used to transmit information signals from the wireless node to the access point, and the signal-to-interference ratio of the information signal received by the wireless node is obtained by using the same beamforming m...

Abstract

The invention discloses a method for rapidly evaluating the information transmission interruption probability in wireless power supply communication. The method is characterized by comprising the steps of: (1), MIMO transmission WET, realizing WET through an MINO technology: pre-coding a PB, and sequentially performing transmitting end mapping, MIMO transmission and receiving end mapping to obtaina wireless node energy signal; (2), MIMO transmission WIT, realizing WIT through the MINO technology: transmitting an information signal between a wireless node and an access point by adopting MIMO,and obtaining the signal-to-interference ratio of the information signal received by the wireless node by utilizing a beam forming method same as the WET; and (3), the information transmission interruption probability: obtaining the expected value of the information transmission interruption probability of the WIT by calculation. The method disclosed by the invention has the advantages that: the information transmission interruption probability of the system can be evaluated accurately and rapidly; and influence of the system parameters of a network on the information transmission interruptionprobability is revealed.

Description

technical field [0001] The invention relates to a method for rapidly evaluating information transmission interruption probability in wireless power supply communication, and belongs to the technical field of energy collection in wireless communication. Background technique [0002] Considering the large-scale distribution of PBs to transmit energy for wireless nodes, the wireless nodes use the collected energy to transmit information and upload the information to the access point. PBs, wireless nodes, and access points all have multiple antennas for transmission. The overall communication process is divided into two stages, the first stage is the WET process from the PB to the wireless node, and the second stage is the WIT process from the wireless node to the access point. In the WIT process of the second stage, the same-channel interference received by the access point is also considered in the network model, and the interference source is other wireless nodes randomly di...
