Problems solved by technology

[0003] Generally in the 4G communication system, the OFDM system is a relatively classic physical layer air interface transmission technology for wireless transmission between the base station and the terminal. In the multiplexing system, sometimes strong narrowband interference (such as hostile malicious interference) exists. When the receiver cannot perceive the interference in time and suppress the interference instantaneously, it may cause the receiver to fail to decode when receiving data, and more serious It can even cause communication interruption between receiver and sender

Abstract

The present application relates to a strong narrowband interference suppression method, device, communication equipment and storage medium. The method includes: performing channel estimation on the received signal based on P reference signals to obtain P estimated channel matrices; dividing the P estimated channel matrices into L groups, and calculating the channel estimation energy of each group of estimated channel matrices; The channel estimation energy of the channel matrix determines whether there is interference in each group of channels at each time, and based on the interference determination result and at least one group of estimated channel matrices, determines the local channel matrix corresponding to each group of channels at each time; using the local channel corresponding to each group of channels The matrix and the estimated channel matrix corresponding to each group of channels are used to calculate the strong narrowband interference signal at each moment, and use the strong narrowband interference signal to perform interference suppression on the received signal. The method can be used to perform fast and instantaneous interference suppression on the received signal, thereby effectively improving the terminal's ability to decode the received signal.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, communication device and storage medium for suppressing strong narrowband interference. Background technique [0002] With the continuous development of communication technology, people have higher and higher requirements for the transmission rate of communication data. From the initial 2G upgrade to 3G, and then from 3G to 4G, now, with the third generation partnership project 3GPP to The establishment of 5G standards, the upgrade of communication technology from 4G to 5G, and the commercialization of 5G will also develop rapidly. [0003] Generally in the 4G communication system, the OFDM system is a relatively classic physical layer air interface transmission technology for wireless transmission between the base station and the terminal. In the multiplexing system, sometimes strong narrowband interference (such as hostile malicious interference) ...
