Coursework Assignment
2024-2025
Design and Analysis of Image Communication System
(Maximum Marks: 50)
Issue date: 16/10/2024
Submission deadline: 13/12/2024 noon
Feedback date: 08/01/2025
Aim: In this assignment, you will design, implement, and test an image communication system consisting of a channel coder, modulator, demodulator, and channel decoder. You will use MATLAB for your implementation.
What to submit: Your coursework must be submitted as a report in Word format. Your MATLAB codes must be provided as text (not pictures) and included as appendices at the end of the report. All code lines must be commented to explain them. Your answers must be supported by references as appropriate. All references must be in IEEE style. Please note that 5 marks will be allocated to the presentation and organisation of your report. Your report, excluding the cover page and MATLAB codes, must not exceed eight pages (minimum font size 11 pt).
1) Design and implement in MATLAB a communication system that uses channel coding with an LDPC code and digital modulation with QPSK to transmit digital images over an additive white Gaussian noise (AWGN) channel. Your system must be implemented as a function. You must clearly describe all the components of your system and motivate your design.
[20 marks: Design: 10 marks, quality of the implementation: 10 marks]
2) Use your system to simulate the transmission of the image Fruits.jpg. Discuss the results.
[10 marks: Design of the simulation: 2 marks, discussion of the results: 8 marks]
3) Replace the LDPC code with a Turbo code and compare the results to those in 2).
[15 marks: Design: 3 marks, quality of the implementation: 4 marks, discussion of the results: 8 marks]
