<p>A bandwidth-hopping spread spectrum (BHSS) method and device is described for mitigating the effects of jamming in wireless communication. According to the BHSS method, a signal is spread, for example using a DSSS technique, to form a sequence of hops 10, 20, 30 whose spread bandwidths 12, 22, 32 are modulated in dependence on a pseudo-random function. The BHSS hops may also be frequency modulated such that the channel frequencies f c1 , f c2 , f c3 of successive hops vary according to a pseudo-random sequence. Jamming or interference signals may be substantially filtered out by a receiver having information about the BHSS modulating sequence(s) used for transmission.</p> |
