Abstract

The invention provides a channel estimation method based on deconvolution and denoising convolution, and relates to the technical field of communication. According to the invention, pilot frequency point information is obtained based on original channel information, interpolation processing is carried out on the pilot frequency point information through a deconvolution network, initial complete channel information is fitted, denoising processing is realized through a denoising convolution network DnCNN, and a channel estimation value is obtained. According to the invention, interpolation fitting is carried out on pilot channel information by using a deconvolution network; the associated information among the pilot frequency point information is effectively utilized; according to the channel estimation method and device based on the DnCNN, in the channel estimation process, the influence of data distortion and channel noise is effectively reduced, and therefore the precision of channelestimation is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a channel estimation method based on deconvolution and denoising convolution. Background technique [0002] Channel estimation is a technique for estimating channel information, and it is a key technique for realizing a wireless communication system. In simple terms, channel estimation is the process of estimating the model parameters of an assumed channel model from the received data, and it is a mathematical representation of the influence of the channel on the input signal. Widely used in mobile communication, wireless transmission and other fields. [0003] Frequency-domain channel estimation is a common channel estimation method in the prior art. Frequency-domain channel estimation is a method of obtaining channel frequency-domain response at each resource element position by using pilot symbol estimation and interpolation operations. The method is to insert pilot i...
