Abstract

The invention discloses a filtering method, a communication device, a chip and module equipment thereof. The method comprises the following steps: receiving a signal from a target sub-channel in a downlink channel, wherein the downlink channel comprises a plurality of sub-channels, and the target sub-channel is included in the plurality of sub-channels; and filtering the signal according to the frequency domain filtering coefficient corresponding to the target sub-channel to obtain a channel estimation matrix of the downlink channel. By implementing the method provided by the embodiment of the invention, the receiving performance can be improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a filtering method, a communication device, a chip and module equipment thereof. Background technique [0002] In wireless communication, due to factors of the signal itself (such as: reflection or refraction) and environmental factors (such as: physical obstacles, weather), etc., there will be interference signals (such as: noise) in the received signal. At this time, the received signal needs to be processed, such as filtering, to filter out the interference signal and obtain the useful signal. However, filtering errors will lead to poor reception performance, and even make it impossible to restore the signal, affecting the transmission quality of the signal. Therefore, how to reduce the error of the filtering result and obtain a more accurate channel estimation in the frequency domain to improve the receiving performance has become an urgent problem to be ...
