Design and Implementation of FHSS (Frequency Hopping Spread Spectrum ) Synthesizer

This work aims to design and implement a secure frequency hopping spread spectrum system (FHSS) on an FPGA. Design is modelled using the Verilog HDL module. In this work, Xilinx ISE Design suite 14.4 software is used along with the ModelSim simulator and XST synthesizer. The core of the FHSS transmitter is a Direct Digital Synthesizer (DDS) which generate desired frequency signal. This is a very secure communication system because its carrier frequency changes at every fixed interval in a Pseudo-Random manner. In this work, the simulation and synthesis procedure of a frequency hopping binary frequency shift keying (FH/BFSK) spread spectrum system is designed and described.
