Assignment Task:

Module Title: Radio and Optical Communication Systems 

Assessment Title: Modelling and Analysis of a Radio over Fibre Link

Main objectives of the assessment: To consider the operation of radio over fibre communication systems and it’s integration into wireless communications networks 

Brief Description of the assessment: This assignment will concentrate on modelling a radio over fibre communication system in MATLAB Simulink environment and Learning outcomes for the assessment: 

a) Comprehensive understanding of Radio over fibre concepts in communication systems 

b) Ability to model a Radio over fibre link 

c) Ability to critically analyse and evaluate performance in RoF systems 

d) Awareness of regulatory requirements related to RF emissions. 

2 Objectives and Learning Outcomes Main objectives of the assessment:

To consider the operation of radio over fibre communication systems and its integration into wireless communications networks 

This assignment will contribute towards the following learning outcomes 

1. Comprehensive understanding of Radio over fibre concepts in communication systems 

2. Ability to model a Radio over fibre link 

3. Ability to critically analyse and evaluate performance in RoF systems 

4. Awareness of regulatory requirements related to RF emissions. 

The following tasks need to be completed for this assignment 

1) Discuss the benefits of radio over fibre in modern communication networks as part of the introduction to this assignment report. 

2) Task 1: Formulate the fibre link on the outline model and analyse the performance with different fibre lengths for a fibre loss, alpha of -0.00xx; (xx: last two digits of your student number). Details of the model employed and a BER vs fibre length plot is expected as part of this analysis. Please remember that you need to run the simulation for a sufficient duration to obtain better accuracy. For example, for a BER of around 10-5 the model needs to be run long enough to obtain at least 105 data bits. Also, use a better resolution for the distance (distance step) when carrying out this analysis. 

3) Task 2: Formulate the radio link on the outline model and set the fibre length to 100 + xx km 

(xx: last two digits of your student number). 

i. Provide details of the model introduced. 

ii. Discuss the effects on data signal when it travels through the model subsystems giving appropriate scope displays and identify the assumptions made in this model. 

iii. Analyse the performance for different transmitter and receiver separations and identify the separation that will give a BER around 10-4. 

iv. Critically discuss techniques that can be employed to increase the separation distance on the RF link. 

4) Task 3: Discuss emission guidelines that need to be followed when using wireless schemes and analyse whether your computation in Task 2) iii. meets emissions requirements. 

5) Task 4: Formulate a direct intensity-modulated RoF scheme and compare its performance with the model in task 2. Details of the model employed with justifications and a BER vs fibre length plot is expected as part of this analysis
