Process in Week1
Introduction:
Due to the impact of the pandemic, it was suggested by the department that all group projects this year were to be based online, the project that we were assigned required us to conduct experiments and operations on MATLAB. This project will simulate the noise in wireless communication, create some methods to reduce the noise, and analyse the performance of the noise system.
Main purpose：
The main purpose of the project is to analyse the performance of two noisy systems. The first one is the system transmitting bipolar and unipolar NRZ signalling through a channel with additive white Gaussian noise (AWGN) in presence only. The second one is the system transmitting signalling through a channel with both AWGN and fading effect.
Objective:
1. Have a general ideal about the definition of additive white Gaussian noise and the two kinds of common line codes used in digital baseband transmission. (which are unipolar NRZ and bipolar NRZ codes)
2. Understand the ways of evaluating a noise system. (i.e., understand the definition of bandwidth efficiency, channel capacity, Shannon’s theorem and bit error rate.)
3. Understand the simplified model of the binary digital transmission.
4. Build a rough simulation process.
5. Allocate the roles.
Week1:
The task of the first week is mainly to read related materials and have a certain understanding and ideas about the project. At the academic advisor meeting every Wednesday, our academic advisor sent us reading documents related to the project,and there are four things what we have done:
1. We have finished reading the material 1and 2 provided by our academic advisor.
2. The example code of simulating the communication systems with MATLAB was fully understood.
3. A rough simulation process was built successfully.

4. Discussions were held so that we could plan how we were going to approach this project. We set out some roles for the future of the project e.g. those who would be working on the poster towards the end of the project. Xinlu volunteered to make a ‘start’ on the code so that we could help to make improvements over the course of the project.
The report, which would likely be the most significant deliverable of the project, will be produced on Google Docs so that all members can contribute.
Next Week:
We discussed 2 objectives in the meeting that we would all aim to do by week 2 and these were:
1. To keep reading materials and learn about fading effect.
2. Produce some code to simulate the wireless communication system.
