This document presents a summary of a student's project on analyzing the performance of OFDM over AWGN and Rayleigh channels using MATLAB simulation. The project includes implementing an OFDM transmitter and receiver in MATLAB, transmitting serial data over AWGN and Rayleigh channels, and analyzing the bit error rate performance in both cases. The simulation results show that the bit error rate decreases rapidly with increasing signal-to-noise ratio for the AWGN channel, while it decreases more slowly for the Rayleigh channel. The performance analysis verifies the effectiveness of OFDM transmission over wireless channels.
This Matlab code simulates OFDM channel estimation using a PN sequence as a cyclic prefix. It generates transmitted OFDM signals, adds channel effects using different multipath delay profiles, and estimates the channel using three methods: conventional correlation, correlation with two-tap filter estimation, and interpolation of periodically inserted PN sequences. It compares the bit error rates of the three channel estimation methods under varying signal-to-noise ratios.
The document discusses modeling a 4G LTE system in MATLAB. It provides an overview of 4G LTE standards and features, and presents a case study of modeling the downlink physical layer of an LTE system in MATLAB. Key aspects covered include channel coding, OFDM, MIMO, link adaptation, and options for simulation acceleration and connecting system design to implementation through code generation.
