Abstract
Frequency hopping (FH) is widely used in commercial and military communications. The purposes of FH in military communications are anti-jamming and low probability of interception. To implement low probability of detection or interception, FH signals randomly change carrier frequency. There are several kinds of FH detectors for example autocorrelation detector, maximum-likelihood detector and optimum detection. We focused on FFT-based detector kinds of maximum-likelihood detector. The FFT-based detector can monitor several MHz and more. However, the FFT-based detector suffers from frequency offset problem due to a lack of information of targeted FH signals. To improve the drawback, we propose interpolation estimation of frequency offset. The proposed approach mitigates the effect of frequency offset and increases probability of detection. Furthermore, the proposed approach has low complexity and does not require additional hardware. In this paper, we show the linear interpolation estimation of frequency offset and compare it with conventional detector in probability of detection.
