Orthogonal Time Frequency Space (OTFS) modulation is a candidate waveform for future mobile networks. The main idea of OTFS is to modulate the information symbols on different delay-Doppler resources through a two-dimensional transfomation. Through this design, improved performance and low receiver complexity is promised in scenarios where high Doppler shifts disturb the transmission quality. 

Communication between a LEO satellite and a ground terminal is a typical example which suffers from high Doppler shifts and long propagation delays. Therefore, OTFS seems a promising modulation technique for future satellite communication systems.


In this thesis, the practicability of OTFS for satellite communication shall be investigated.

Depending on the pre-knowledge, different aspects of OTFS can be analyzed.


Good understanding about the fundamentals of communication as well as good mathematical skills are essential for this thesis. Furthermore, programming skills in Python or Matlab are necessary.

For masterproject, basic knowledge about OFDM, wave propagation and channel modeling is expected.
