LTE Channel Estimator Source Code Implementation in MATLAB

This repository contains MATLAB source code for an LTE channel estimator. The implementation focuses on estimating channel characteristics and parameters in LTE systems using various algorithms. The codebase likely includes key components such as reference signal processing, least squares (LS) or minimum mean square error (MMSE) estimation techniques, and channel interpolation methods across time and frequency domains. The implementation may feature functions for handling different LTE transmission modes, processing cell-specific reference signals (CRS), and generating channel state information (CSI) reports. The estimator typically employs pilot-based estimation where known reference signals are used to derive channel response at pilot positions, followed by interpolation to estimate the complete channel matrix. Key MATLAB functions may include signal demodulation, covariance matrix calculations, and noise variance estimation for improved accuracy in different signal-to-noise ratio (SNR) conditions.
