Embodiment Construction

[0020] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below with reference to the accompanying drawings.

[0021] like figure 1 As shown, the method of the present invention specifically comprises the following steps:

[0022] S1. Determine a broadband multipath channel model.

[0023] The channel model is shown as figure 2 As shown, the channel between the transmitter and receiver is rich in scatterers with multiple resolved paths. The signal bandwidth is B, and the speed of light in vacuum is c. When the difference between two adjacent propagation paths is less than or equal to c / B, the two propagation paths are indistinguishable at the receiving end. When the difference between the two adjacent propagation paths is greater than c When / B, the two propagation paths can be distinguished at the receiving end. The small-scale fading amplitudes of ea...

Abstract

The invention discloses a single-user broadband wireless data energy transmission method based on waveform shaping technology, which is applied to the technical field of digital-energy integrated communication network, and the downlink throughput of simultaneous transmission of wireless information energy for existing broadband signals is not high. The transmitter of the present invention sends the waveform-shaped signal to the receiver through the broadband multipath channel, and the receiver uses a signal divider to divide the received signal in the power domain. The divided signal includes two parts, wherein One part is used for energy collection, and the other part is used for information decoding. By optimizing the transmission waveform shaping and the power division of the received signal, the downlink throughput can be maximized under the condition that the receiving current of the receiver is satisfied.

Description

technical field [0001] The invention belongs to the technical field of data-energy integrated communication network, and in particular relates to a single-user broadband wireless data energy transmission strategy design based on waveform shaping technology. Background technique [0002] With the rapid development of communication technology and the emergence of large-scale Internet of Things, its rapid development and application fields involve all aspects, effectively promoting the development of infrastructure fields such as industry, agriculture, and security, and making limited resources more rationally allocated. People's daily life is inseparable from the Internet of Things. In the future, the extensive progress of the Internet of Things in various applications will inevitably increase the energy consumption of network equipment. At present, tens of billions of devices have joined the Internet of Things in the world, and these devices require a lot of energy to work, a...
