Overview
Task Assignment: Satellite Communication System Design & Simulation
You are required to design and simulate a complete satellite communication system operating in a geostationary orbit (GEO) using MATLAB. The system must be tailored for data communication within the Sultanate of Oman, with the receiver located in Muscat.
---
### 1. System Design
Design a full satellite communication link that includes:
- Ground Station (Transmitter & Receiver)
- Geostationary Satellite (GEO)
- Uplink and Downlink paths
The system must operate within the S-Band (2–3 GHz). Clearly define:
- Uplink frequency
- Downlink frequency
- Orbital position of the satellite
- Elevation angle relative to Muscat
---
### 2. Channel Modeling (Losses & Impairments)
You must model a realistic lossy communication channel by including:
- Free Space Path Loss (FSPL)
- Atmospheric Attenuation (especially sandstorms and rain in Oman)
- Depointing Losses (antenna misalignment)
- Polarization Mismatch Losses
- Thermal Noise
- Radio Frequency Interference (RFI)
You may ignore:
- Doppler Shift
- Faraday Rotation
- Fog/Ice attenuation
- Multipath effects
---
### 3. Link Budget Calculation
Develop a complete Link Budget including:
- Transmit Power (Pt)
- Antenna Gains (Gt, Gr)
- Total Losses
- Received Power (Pr)
- Noise Power (N)
- Signal-to-Noise Ratio (SNR)
Ensure the system achieves reliable communication under worst-case conditions.
---
### 4. MATLAB Simulation
Build the system using:
- MATLAB Communications Toolbox
- RF Blockset
Your simulation must include:
- Transmitter block
- Channel with all losses and noise
- Receiver block
- Block diagram
- Signal flow between components
---
### 5. System Design Choices
You must justify all design decisions, including:
- Multiple Access Technique (choose one: FDMA / TDMA / CDMA)
- Modulation Scheme (e.g., QPSK, BPSK)
- Error Correction Technique (e.g., FEC)
- Antenna types and parameters
---
### 6. Performance Evaluation
Analyze system performance using:
- Bit Error Rate (BER)
- Throughput
- Capacity
- Outage Probability
Provide graphs and simulation results from MATLAB.
---
### 7. Oman Context Consideration
The system must be adapted for Oman by considering:
- Environmental effects (dust, sandstorms)
- Geographic coverage
- Practical implementation challenges
---
### 8. Final Deliverables
Prepare a report (max 4000 words) including:
1. Abstract
2. Objectives
3. Literature Review
4. System Design
5. Link Budget Calculations
6. MATLAB Simulation Model
7. Results and Analysis
8. Conclusion
9. Individual reflection 4 students
---
### 9. Additional Requirements
- Include diagrams of the system
- Include MATLAB screenshots or outputs
- Clearly explain each block in the system
- Highlight assumptions and trade-offs
---
### 10. Expected Outcome
The final system must demonstrate a fully functional satellite communication link capable of reliable data transmission in a lossy environment.

Make sure the work is clear, well-structured, and technically accurate. All calculations and simulation results must be justified and explained.
