Overview

This repository contains the source code related to Optical Wireless Communications System and Channel Modelling with MATLAB.

Some of the original code had issues and required modifications. I have made the necessary adjustments to enhance practicality and functionality.

MATLAB Version

MATLAB R2024a

Directory Structure

• util/ - Utility scripts and functions.

Some Code Descriptions

Below is a list of the MATLAB scripts included in this repository (not all):

Name	Description
CORRECT_plot_Fig3p31.m	The gamma-gamma probability density function (PDF)
CORRECT_plot_Fig3p28.m	PDF of log-normal distribution
CORRECT_program_4p4.m	Program 4.4: MATLAB code to simulate Bit Error Rate (BER) of On-Off Keying Non-Return-to-Zero (OOK-NRZ)
CORRECT_program_4p5.m	Program 4.5: MATLAB code to simulate BER of OOK-NRZ using a matched filter-based receiver
CORRECT_plot_Fig4p13.m	Program 4.10: MATLAB code to calculate Power Spectral Density (PSD) of Discrete Pulse Interval Modulation (DPIM) (0 Guard Slot)

Usage

To use these scripts, ensure that util/ is included in your MATLAB path. This can be done by adding the following line to your MATLAB startup script or running it directly in the MATLAB command window:

addpath('path/to/util');

Replace 'path/to/util' with the actual path to the util/ directory.
