GalSimBorras-Jan2003.pdf GalileoSim The objective of the activity was to develop a signal generator for GALILEO and GPS signals. At first, a software signal generator was implemented in Matlab. The software signal generator has to serve to rapidly prototype different transmitter configurations, algorithms and techniques, assess the performance of GALILEO signals, and create initial designs for further hardware implementations. Then, the signal generator was ported to VHDL code. A hardware implementation, e.g. on FPGA, will introduce higher efficiency due to its higher processing speed, allowing real-time generation of the signal.
