System and method for presence and synchronisation detection of a signal for a frequency hopping system working in a perturbed environment |
摘要 |
The process involves correlating a received signal with a reference signal R and storing K with bigger values of the signal and their correction position with a known tag for each reference frequency. The values selected among K corresponding to the position are summed and the highest sum is retained. The highest sum is compared with a threshold value and producing a detection signal when the sum is above threshold. An Independent claim is also included for a detection and synchronization device for a signal in a frequency hopping system.
