### Task Description

You are required to complete a comprehensive technical report on the topic Co-channel Interference Cancellation (CCI Cancellation) as part of the Mobile & Wireless Communications module. The objective of this assignment is to investigate the problem of interference in cellular systems and propose effective methods to mitigate it using theoretical analysis and MATLAB-based simulation.

This is a group report (3000 words) along with an individual reflection (500 words) 5 students , as specified in the assignment brief .

### Objectives

You are expected to:

1. Demonstrate a clear understanding of co-channel interference (CCI) in cellular networks.

2. Analyze the causes and impact of interference on system performance.

3. Explore and evaluate different interference cancellation techniques.

4. Design and implement a MATLAB/Simulink simulation model of a wireless communication system.

5. Compare system performance before and after applying interference cancellation.

6. Critically analyze results and provide justified conclusions.
