Keselamatan komunikasi tanpa wayar semakin penting pada masa kini. Modulasi arah (DM) dilihat sebagai teknologi keselamatan lapisan fizikal tanpa wayar yang menjanjikan. DM Tradisional ialah teknologi sisi pemancar yang menayangkan isyarat maklumat termodulat secara digital ke arah yang dikehendaki (atau di lokasi yang dikehendaki) sambil serentak memesongkan format buruj isyarat yang sama ke arah lain (atau di semua lokasi lain). Walau bagaimanapun, isyarat maklumat termodulat digital yang terdedah secara langsung ini mudah dipintas oleh penyadap di sepanjang arah yang dikehendaki (atau di sekitar lokasi yang dikehendaki). Skim DM baharu untuk komunikasi titik-ke-berbilang titik selamat berdasarkan tatasusunan pelbagai frekuensi ortogon berbantu spektrum sebaran (singkatan untuk SS-OFDA-M-DM) dicadangkan dalam kertas kerja ini. Ia boleh mencapai komunikasi selamat titik-ke-berbilang titik untuk berbilang penerima koperasi di lokasi yang berbeza. Dalam cadangan skim SS-OFDA-M-DM, hanya pengguna koperasi yang menggunakan penerima DM tertentu dengan parameter spektrum sebaran yang betul boleh mendapatkan simbol yang betul. Pendengar tanpa pengetahuan tentang parameter spektrum sebaran tidak boleh memintas isyarat berguna secara langsung di lokasi yang dikehendaki. Selain itu, mereka tidak boleh menerima simbol biasa di lokasi lain sama ada walaupun parameter spektrum sebaran yang betul diketahui. Keputusan simulasi berangka mengesahkan kesahihan skim yang dicadangkan kami.

Abstract: Wireless communication security has been increasingly important nowadays. Directional modulation (DM) is seen as a promising wireless physical layer security technology. Traditional DM is a transmit-side technology that projects digitally modulated information signals in the desired directions (or at the desired locations) while simultaneously distorting the constellation formats of the same signals in other directions (or at all other locations). However, these directly exposed digitally modulated information signals are easily intercepted by eavesdroppers along the desired directions (or around the desired locations). A new DM scheme for secure point-to-multipoint communication based on the spread spectrum assisted orthogonal frequency diverse array (short for SS-OFDA-M-DM) is proposed in this paper. It can achieve point-to-multipoint secure communication for multiple cooperative receivers at different locations. In the proposed SS-OFDA-M-DM scheme, only cooperative users that use specific DM receivers with right spread spectrum parameters can retrieve right symbols. Eavesdroppers without knowledge of spread spectrum parameters cannot intercept useful signals directly at the desired locations. Moreover, they cannot receive normal symbols at other locations either even if the right spread spectrum parameters are known. Numerical simulation results verify the validity of our proposed scheme.
