| Abstract: | Frequency Hopping Spread Spectrum(FHSS) communication is widely used,especially in the field of military communication,because of its better ability in anti-interference and net-working,so blind detection signals of FHSS system are considered as important contents in communication counter measures.A blind detection algorithm of FH signal based on the correlation in the frequency domain is proposed.The algorithm can be implemented without any prior information.The effectiveness of the algorithm at low SNR is... |
