Abstract
In order to efficiently mitigate the interference of directional jammers, we investigate a beam-hopping (BH) communication scheme, which includes slow beam-hopping (SBH) and fast beam-hopping (FBH) schemes. In the BH communication scheme, only one pair of the beams is used for transmission and it hops from one to the next according to an assigned BH pattern. In this contribution, a range of expressions in terms of the symbol error rate (SER) performance of the BH and conventional single-beam (SB) schemes have been derived, when both the downlink and uplink are considered. The SER performance of the BH scheme is compared with that of the SB scheme, for M-ary phase-shift keying (MPSK) and M-ary quadrature amplitude modulation (MQAM) signals under composite log normal shadowing/Nakagami-m fading channels. Our analysis and results show that the proposed BH scheme is suitable for communications, when several distributed antenna arrays are available around a mobile.
