Embodiment Construction

[0030] The invention is further clarified in conjunction with the accompanying drawings and specific embodiments, and it is to be understood that these examples are intended to illustrate the invention only and are not intended to limit the scope of the invention, and those skilled in the < The modification of the equivalent form falls in the range as defined in the claims appended claims.

[0031] The application scenario of the present invention is like figure 1 As shown: During the information bits transmission, the user terminal employs the transmission information to the RRH transmission information, and the RRH transmits the information bit transmitted by the user terminal to quantize, and then employs the time division multiplexing technology through the wireless forward link. Transfer your packet to the calculation center. Suppose all user terminals will send bit data signals to all RRHs.

[0032] like figure 2 As shown, the present invention includes three stages, τ 1 Tim...

Abstract

The invention discloses a resource allocation method of a distributed wireless energy and information transmission system. Finally, on the premise that the total transmission delay is minimized and the signal-to-noise ratio requirement is met, the resource optimization problem in the wireless energy simultaneous transmission scene is solved. At a user side, bit data signals are uniformly sent to an RRH side for processing in a time division multiplexing sending mode; at an RRH end, firstly, energy is sent to a user through a beam forming technology, and then received bit data signals are uniformly sent to a cloud end for processing after being subjected to spatial filtering and a k-nearest neighbor algorithm; and at the cloud, diversity reception is carried out on the received data information and the data information is finally sent back to the user side. In the spatial filtering, the received user signals are processed by using a vector quantization method, so that the task calculation efficiency is improved.

Description

Technical field [0001] The present invention belongs to the field of wireless communication, and more particularly to a resource allocation method of distributed wireless energy and information transmission system, more particularly to a resource allocation method based on alternating optimized distributed wireless energy and information transmission system. Background technique [0002] In recent years, the development of the Internet of Things (IOT) has stimulated a new application (such as virtual reality, enhanced reality, automatic driving), providing real-time machine, machine-to-machine interaction. These applications have delayed sensitivity, depending on real-time communication and calculation of a large number of wireless terminals. In the Internet of Things network, a large number of wireless devices having calculation and communication capabilities are deployed. These wireless devices often have limited equipment life. Therefore, how to solve this key performance limi...
