Design and Development of a Software Defined Radio for Ecuadorian Army, trough the use of a USRP and Simulink tool of Matlab

Abstract:

This research presents a design of a software defined radio using the USRP and Simulink software of Matlab. Based on voice digitalization, it was considered necessary to implement the codec G. 726 of ITU, in 32 Kbps version, to perform the respective comparison with 64 Kbps G. 711 codec, which was developed as a Simulink's block set. To provide sturdiness to the system, it was used an appropriate channel coding. This was achieved through the use of block codes and interlaced or Trellis, such as Convolutional codes. Finally, both systems are proposed with QPSK modulation and frequency modulation, with the hope of providing a significant contribution and comparative development to SDR systems, through the assessment by the BER.
