Problems solved by technology

[0006] However, in practical application, the inventors of the present invention have found that the existing communication system based on QSM technology has a large amount of decoding calculation at the receiving end, resulting in a low transmission rate of the system, which limits the application of the communication system based on QSM technology
For example, in the ESL (electronic price label) system, the wireless communication sending and receiving method is the key to the exchange of information between the electronic price tag and the server, and the existing communication system based on QSM technology cannot complete the electronic price tag and server in time due to the low transmission rate. The information interaction between servers cannot be applied to the ESL system

Abstract

The invention discloses an ESL system, a wireless communication system, a receiving terminal of the wireless communication system and a signal receiving method of the wireless communication system. The method comprises the following steps: receiving signals received by a receiving antenna and sent by a sending terminal through an orthogonal spatial modulation QSM technology; demodulating the received signals to obtain received complex symbols; and decoding the received complex symbols by using a sphere decoding detection algorithm to obtain transmission information. Through adoption of the method, the decoding calculation quantity of the receiving terminal can be reduced, and the transmission rate of the system can be increased.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an ESL system, a wireless communication system, a receiving end thereof, and a signal receiving method. Background technique [0002] MIMO (Multiple-Input Multiple-Output) technology refers to the use of multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, so that signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving communication quality . It can make full use of space resources, realize multiple transmissions and multiple receptions through multiple antennas, and can double the system channel capacity without increasing spectrum resources and antenna transmission power, showing obvious advantages, and is regarded as the next generation of mobile The core technology of communication. [0003] SM (Spatial Adjustment) technology, a...
