Abstract :
A new signal will be used within the modernized satellites for the global positioning system (GPS) as well as within the launch of the new European global navigation satellite system (GNSS) called Galileo, this signal will use the binary offset carrier (BOC) modulation scheme. BOC signals have very attractive features such as better tracking and immunity to multipath, as well as it will co-exist with current GNSS signals with minimal interference. This paper presents the design and implementation a programmable multi-coded BOC(m,n) signal generator for the use in navigation systems. The design is verified on an FPGA for functionality. Measurements show the correct functionality of this signal generator for both Gold codes and the large set of Kasami codes.
