A communication system, method, device and storage medium

Abstract

Embodiments of the present invention provide a communication system, method, device, and storage medium. The system includes: a base station, a reflecting surface, and multiple user terminals, wherein each user terminal broadcasts a pilot signal; the base station receives the first received signal, By analyzing it, calculate its corresponding channel state information, and then determine the target configuration parameters of the reflective surface; the reflective surface adjusts its own configuration according to the target configuration parameters, and obtains the adjusted reflective surface; the base station sends multiple pieces of data to be sent The information is encoded into a data packet, and the base station signal carrying the data packet is broadcast; the adjusted reflector receives the second received signal, and the reflected signal is obtained by applying reflection phase shift and reflection amplitude to it; each user terminal is connected to the third The signal is received, and by decoding it, the data information to be sent corresponding to the user terminal is obtained. In this way, the transmission delay of the communication system can be reduced while controlling the bit error rate as much as possible.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication system, method, device and storage medium. Background technique [0002] A communication system generally includes a source (sending device), a sink (receiving device) and a channel (transmission medium), etc. When the source sends data information (such as sound, image, text, etc.) to the sink, it first encodes the data information, It is transmitted to the sink in the form of a signal through the channel, and the sink decodes the signal to obtain the data information sent by the source. [0003] With the development of communication technology, the requirements for the transmission delay (the time it takes for data information to be sent from the source to the destination) and bit error rate (the index to measure the accuracy of the data information transmitted within a specified time) of the communication system are increasing. For example, the p...

[0005] However, the above scheme ignores that the transmission delay in the communication system is proportional to the code length. The longer the code length, the longer the transmission delay. Moreover, if the user terminal is in a relatively complex environment, such as a city, factory, etc. In the environment, when the signal broadcast by the base station encounters an obstacle, path loss will occur, and the signal power received by the user terminal will be correspondingly weakened, resulting in a decrease in the achievable rate of transmitting data information to be sent in the communication system and an increase in transmission delay
