摘要： A method of fighting interference in a frequency-hopping communication system is disclosed. The system has at least one main sensor and one or more auxiliary sensors. According to at least one embodiment, frequency-hopping signals are received. The frequency-hopping signals are arranged to include useful bands and one or more guard bands inserted between the useful bands, and a ratio of the useful bands to the guard bands being chosen according to a predetermined value of probability of interference interception. Signals of the inserted guard bands having a signal level greater than a predetermined threshold are selected. A set of spatial-filtering weightings are calculated according to a correlation matrix of noise plus jammers alone on the signals selected. Baseband signals of the received frequency-hopping signals are filtered by the set of the calculated spatial-filtering weightings.

摘要： A method for fighting interference in a communication system is disclosed where the links are of frequency-hopping type. The signal has several frequency time slots. The system has at least one main sensor and one or more auxiliary sensors, one or more guard band are inserted between the useful bands of the frequency-hopping signal. The total area of the inserted guard bands is chosen so as to satisfy a chosen value of probability of interference interception. The signals of the inserted guard bands are selected whose level is greater than a given threshold. A set of spatial-filtering weightings are determined, for each time slot of the signal, by taking account of the correlation matrix of the noise plus jammers alone on the signals selected. The baseband signals of the assemblage of extended blocks are filtered by the set of calculated weightings of the time slot so as to generate extended blocks devoid of interference.
