Abstract

The adaptive Frequency-Hopping(FH) technique based on interference sensing can further enhance the anti-interference performance of hybrid Direct-Sequence/FH Spread Spectrum(DS/FH SS) system and FH Orthogonal Frequency Division Multiplexing(FH-OFDM) system. Existing interference sensing algorithms cannot provide an accurate detection performance for both stationary and non-stationary LFM interference, and have the problem of misjudging useful signal as interference due to the dynamic time-frequency characteristics of useful signal. To improve the sensing detection capability with low false alarm rate, this paper proposes an algorithm, by analyzing the duration units of frequency points and combining the least-squares fitting method to sense stationary and non-stationary LFM interference. Simulations have been carried out to demonstrate the effectiveness of our interference sensing algorithm.
