This paper investigates the design of joint frequency offset and carrier phase estimation of a multi-frequency time division multiple access (MF-TDMA) demodulator that is applied to a digital video broadcasting—return channel system via satellite (DVB-RCS). The proposed joint estimation algorithm is based on the interpolation technique for two correlation values in the frequency and phase domains. This simple interpolation technique can significantly improve frequency and phase resolution capabilities of the proposed technique without increasing the number of the correlation values. In addition, the overall block diagram of a digital communications receiver for DVB-RCS is presented, which was designed using the proposed estimation algorithms. Index Terms—Carrier phase estimation, DVB-RCS, frequency offset estimation, interpolation, joint estimation, MF-TDMA.

This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).

There are numerous MATLAB m-files included in this software package. Thus, the the authors have bundled all files and sample data in a *.zip file (KTHorb.zip). The Readme.txt file describes the directories created when the .zip file is unpacked. The file Matlab_implementation.doc (or Matlab_implementation.txt) describes some of the classes and methods included in the package for GPS satellite orbit interpolation.

Software-defined radios (SDRs) have been around for more than a decade. The first complete Global Positioning System (GPS) implementation was described by Dennis Akos in 1997. Since then several research groups have presented their contributions.We therefore find it timely to publish an up-to-date text on the subject and at the same time include Galileo, the forthcoming European satellitebased navigation system. Both GPS and Galileo belong to the category of Global Navigation satellite Systems (GNSS).
