Abstract
The goal of this project is to use MATLAB to model orthogonal frequency division multiplexing (OFDM) modulation technique across 24 kHz, 48 kHz, and 3 MHz bandwidths in the high frequency (HF) radio band (3-30 MHz). The purpose of our design is to make HF long distance communication faster and more reliable so that every part of the world, including the most remote parts, will have access to high speed, long distance wireless communication. Our MATLAB model will allow us to modify the bandwidth, carrier frequency, modulation type, signal to noise ratio (SNR), and image size to determine which combination of parameters provides reliable OFDM data transmissions in the HF radio band. To determine the success of our model, we will calculate the data rate and the bit to error ratio (BER) after data transmission. Ideally, we would like to have a BER of 10-5 for an SNR that is representative of the noise level experienced in the ionosphere. This report describes the current design of our MATLAB model and presents the results for the set of parameters that will achieve the best data transmission in the HF radio band.
