The task: Designing and Simulating a Geo-Stationery orbit Satellite Communications Link for a Lossy Communication Channel
Task Description
This assignment requires the candidates to design and simulate an end-to-end Geo-Stationery orbit satellite communications link over a lossy satellite communication channel using MATLAB simulation software. The primary function of the satellite link is for data communications in Oman. The assignment will involve significant research on the part of the candidates and the design process should be contextualized for use in the Sultanate of Oman.
The primary losses involved in the channel will be:
i) Free space loss
j) Atmospheric attenuation (Sandstroms and rain)
k) Depointing losses
l) Polarization mismatch losses
In addition to these, there will be Radio Frequency Interference and Uplink/ Downlink Thermal Noise.
You can ignore Doppler shift, Faraday's rotation, attenuation due to atmospheric gases (for frequencies less than 10GHz), attenuation due to fog and ice clouds, Scintillation and multipath contributions. You are required to take Round-Trip Time Delay into account as the design is for a Geo-Stationery orbit satellite communications link.
You must select uplink and downlink frequencies in the S Band (3 GHz to 4 GHz) and required to study the constellations, satellite orbital design, angle from satellite to earth station, radio interface among other design criteria with reference to a receiver location in Muscat.
Carry out a link budget design that includes advanced link budget calculations and stipulate antenna parameters, error coding you are using and the multi-access technique you deploy (either code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA) but not space division multiple access (SDMA)). Outline the variations in system design with their respective performances.
The performance metrics that needs to be utilized include outage probability, throughput, bit-error rate, and capacity. The end goal is to design and implement a satellite communications system that achieves high performance and reliable transmission in a lossy medium.
Except for the stipulated conditions above, any other needed criteria can be set by you, but they must be clearly stated.
You are required to submit a report of up to 4000-words for this Task.
The report should include:
1. Your final overall designs demonstrating MATLAB component blocks and connections between them, and application to satellite communications systems.
2. A description of the overall purpose of each component in the design and why is it required. The expected criteria is only the necessity of having such design component in relation to the prescribed task, contextualized with the location of the receiver (Muscat, Oman) and the orbital and frequency stipulations.
3. A detailed description of the design choices and calculations for each component and for the system as a whole. This section should also include results (e.g. graphical or numerical results of simulations) obtained while investigating and refining your design. This might, for example, include a discussion of trade-offs in your design, based on measured performance etc.
4. Demonstration of a final working satellite communications system.
