OFDM Channel Estimation Simulation Based on Training Sequences

This document presents a simulation program for OFDM channel estimation based on training sequences that can be executed directly. The program implements algorithms for accurately estimating OFDM channel characteristics and performance metrics. Using training sequences as input, the code automatically analyzes and calculates various channel parameters including channel fading, multipath delay, and signal distortion through sophisticated signal processing techniques. The simulation employs time-domain training sequence insertion and frequency-domain channel response calculation methods, providing visualizations of channel impulse response and frequency response characteristics. This tool helps users better understand and optimize OFDM system performance by demonstrating practical implementation of least squares (LS) or minimum mean square error (MMSE) estimation algorithms. Whether you are a student or researcher, this simulation program serves as a valuable resource for achieving improved results in channel estimation studies, with modular code structure allowing easy modification of parameters like training sequence length, SNR values, and channel models.
