CONCEPTS¶

This project focuses in the implementation of a satellite communication chain in NI LabVIEW Communications System Design Suite [http://www.ni.com/labview-communications/f/], and demonstrate on two USRPs [http://www.ni.com/pdf/manuals/375839a.pdf]. Transmission and Reception were devised using DVB-S2 [http://www.etsi.org/deliver/etsi_en/302300_302399/302307/01.02.01_60/en_302307v010201p.pdf] standard as syllabus. QPSK modulation was implemented and prior channel coding in BCH and LDPC. The approach was to start with the evaluation of BCH and LDPC coding and calculate the performance of FEC coding in terms of BER, secondly implement Tx and Rx using typical satellite waveforms and observe the QPSK constellations in both transmission and reception, and final merging the two into a communication chain for demonstration and simulation in the two USRPs.
