Problems solved by technology

[0015] From the link selection scheme, it can be seen that in case 1 and case 2, the link is not selected according to the link quality when the buffer area is empty or full, which will lead to mandatory transmission. The disadvantage of this method is that it will reduce System Bit Error Rate Performance
At the same time, this technology assumes that the channel state is known and does not perform channel estimation, which is not suitable for actual communication scenarios

Embodiment Construction

[0080] The embodiment of the present application provides an energy buffer transmission method based on instantaneous channel state information estimation, which is used to solve the technical problem of high transmission bit error rate in the existing wireless energy carrying communication system.

[0081] It should be noted that Simultaneous Wireless Information and Power Transfer (SWIPT) is a new type of wireless communication, which is different from traditional wireless communication that only transmits information. The terminal provides energy. This technology converts a part of the received signal into energy. After a series of conversions, the wireless energy can be stored in the battery of the wireless terminal itself. The captured energy will be used for the normal information interaction circuit of the wireless terminal. power consumption and the power consumption of the energy harvesting circuit. This replaces the inconvenience caused by traditional wired or batter...

Abstract

The energy buffer transmission method based on instantaneous channel state information estimation is applied to mobile Internet and Internet of Things, as well as wireless personal area network and wireless body area network suitable for short-distance communication. Its features: set the "source-relay-destination" double-hop relay system model, the signal transmission format, link selection protocol, and implementation process in the "source-relay-destination" double-hop relay system model. Effect: It has better bit error rate performance, increases the gain by more than 3dB, and is more in line with various communication scenarios with complex environments in actual situations.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to an energy buffer transmission method based on instantaneous channel state information estimation. Applied to the mobile Internet and the Internet of Things, as well as wireless personal area networks and wireless body area networks suitable for short-distance communication. Background technique [0002] Cooperative communication is a communication technology that can effectively increase diversity gain, expand coverage, and improve communication quality of edge users in wireless communication. Each relay node in the network can cooperate with each other to transmit information by using the broadcast characteristic of wireless communication. Traditional cooperative communication is based on time division multiple access. In the sending time slot, the source node sends information to the relay node, and the relay node receives it; in the receiving time slot, the relay node s...
