At the same time, some classical interpolation algorithms based on BEM are presented, including spline interpolation, Sinc interpolation, cubic B-spline interpolation and Lagrange interpolation. BEM Basis Expansion Model . CDL Clustered Delay Line . by simulation in Matlab, Channel estimation is based on the training sequence of bits and whichis unique for a certain transmitter and which is repeated in every transmitted burst [35].

The function returns the channel estimate h, noise variance estimate nVar, and additional information info.

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.

In this algorithm, a relay training sequence is superimposed on the received signals at the relay node to assist the estimation of the second-hop channel matrices. The optimal structure of the source and relay training sequences is derived to minimize the mean-squared error (MSE) of channel estimation.

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. Communication - Channel Estimation Home : www.sharetechnote.com. 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.
