To facilitate the estimation of the channel characteristics, LTE uses cell-specific reference signals (pilot symbols) inserted in both time and frequency. These pilot symbols provide an estimate of the channel at given locations within a subframe. Through interpolation, it is possible to estimate the channel across an arbitrary number of subframes.

Channel Estimation. Describes the algorithms used for channel estimation in the LTE Toolbox™ product and the options available. LTE Downlink Channel Estimation and Equalization. This example shows how to use the LTE Toolbox™ to create a frame worth of data, pass it through a fading channel and perform channel estimation and equalization.

Home » Source Code » LS channel estimation based on BEM (extended model) LS channel estimation based on BEM (extended model) Matlab Matlab: Download: To create an estimation of the channel over the duration of the transmitted resource grid lteDLChannelEstimate is used. The channel estimation function is configured by the structure cec . lteDLChannelEstimate assumes the first subframe within the resource grid is subframe number enb.NSubframe and therefore the subframe number must be set prior to calling the function. Compare and Visualize Various Channel Estimations. You can perform and compare the results of perfect, practical, and neural network estimations of the same channel model.

Through interpolation, it is possible to estimate the channel across an arbitrary number of subframes.

This allows channel estimation for the subframe of interest to be aided by the presence of pilot symbols occupying the same resource block in subframes before and/or after that subframe.

These pilot symbols provide an estimate of the channel at given locations within a subframe.
