The channel estimator gives 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. Perfect estimator is the simplest algorithm to estimate the channel matrix. By setting the noise equal to zero in (1), the perfect approach estimates the channel matrix as In this way the channel matrix is simply will be obtained by inverse matrix of S/Y. Least Square Algorithm: In this case we estimate the free noise MIMO channel perfectly. channel = nrTDLChannel; channel.NumReceiveAntennas = 1; channel.SampleRate = ofdmInfo.SampleRate; channel.DelayProfile = 'TDL-C'; channel.DelaySpread = 100e-9; channel.MaximumDopplerShift = 20; Obtain the maximum number of delayed samples from the channel path by using the largest delay and the implementation delay of the channel filter. 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.

This MATLAB function performs perfect channel estimation for a system configuration given structures containing the cell-wide settings, and the propagation channel configuration. This MATLAB function performs perfect channel estimation. Slot number, specified as a nonnegative integer.

As I explained in other pages, in all communication the signal goes through a medium (called channel) and the signal gets distorted or various noise is added to the signal while the signal goes through the channel. This example shows how to use CSI-RS to perform channel estimation which forms the basis of CSI acquisition.
