Abstract

The invention discloses a method, device and system for correcting communication information errors. All the method, device and system can be used for acquiring channel estimation quality information reflecting channel estimation quality, therefore, the channel estimation quality information can be used for carrying out error correction on downlink channel information to be sent and transmitting the downlink channel information subjected to the error correction. The error correction can be used for compensating communication errors caused by the problems of jamming and the like in a communication process, and therefore, by means of the method, the device and the system provided by the invention, the communication errors caused by communication jamming and other problems can be effectively decreased, and the communication quality can be effectively improved.

Description

technical field [0001] The invention relates to the field of multiple-input multiple-output wireless communication, in particular to a communication information error correction method, device and system. Background technique [0002] A precoding technology is applied in a current MIMO (Multiple Input and Multiple Output) system to support communication. In general, using precoding technology to multiplex multiple data streams and antennas can make more effective use of existing channel resources, improve system capacity by allocating power to data streams, and reduce the gap between data streams. interference, improving the overall performance of the system. Because the precoding technology can effectively improve the channel capacity, it has become a technology that has attracted much attention, so the precoding technology has become a new research hotspot. [0003] The basic idea of ​​the precoding method for multi-users is that the transmitter at the transmitter knows ...
