A proposal of FH-SS synchronization with FPGA multichannel correlator implementation

This paper presents a proposal for code synchronization for frequency agile systems based on the use of a real-time clock and a multi-channel digital correlator. The proposed synchronization scheme ensures reliability, short synchronization times and resistance to electronic interference and interception. In addition, a proposal for a multi-channel digital correlator has been developed and implemented for use in the synchronization scheme. This type of correlator is suitable for code synchronization in spread spectrum communication systems (DS-SS and FH-SS). The implemented correlator was later used to measure the false alarm probability and the detection probability of the code sequence. Finally, simulation and measurement results are summarized and presented graphically.
