Chapter 7: Multiple Access to a Satellite


Here is the work-script for chapter 7 (slides)


6 December 2021
We started on Chapter 7 and learned about single access and multiple access. For multiple access the footprint of a satellite is important. Click here for examples for Anik F1 and other satellites and the associated eirp contours. With the eirp values the corresponding earth station antenna sizes are also given. We qualitatively described FDMA, TDMA and CDMA. These acronyms describe different features of the satellite communications traffic. We talkes about advantages and disadvantages and how their aspects are related to the [C/N] ratio. And that is where this course ended. Good luck to you all with the final exam.
