A segurança das comunicações sem fio tornou-se um tema quente nos últimos anos. A modulação direcional (DM) é uma técnica de comunicação segura promissora que tem atraído a atenção de muitos pesquisadores. Várias matrizes diversas de frequência (FDAs) diferentes são usadas para obter os sinais DM dependentes da faixa de direção em literaturas anteriores. No entanto, a maioria deles não é ideal o suficiente para obter uma área segura não periódica em forma de ponto. Neste artigo, o arranjo diverso de frequência multiportadora simétrica com incremento de frequência logarítmico, denominado simétrico-multilog-FDA, é usado para obter os sinais DM dependentes da faixa de direção que são normais nos locais desejados enquanto desordenados em outros locais. Com base no multilog-FDA simétrico, derivamos a expressão de forma fechada do vetor ponderado em banda base usando a abordagem de forçamento zero auxiliada por ruído artificial. Em comparação com os esquemas anteriores, o esquema proposto pode obter uma área segura em forma de ponto não periódica com foco mais preciso no local desejado. Além disso, pode alcançar uma comunicação segura ponto-multiponto para múltiplos receptores cooperativos em diferentes locais.

Abstract: Wireless communication security has become a hot topic in recent years. The directional modulation (DM) is a promising secure communication technique that has attracted attentions of many researchers. Several different frequency diverse arrays (FDAs) are used to obtain the direction-range-dependent DM signals in previous literatures. However, most of them are not ideal enough to obtain a nonperiodic dot-shaped secure area. In this paper, the symmetrical multi-carrier frequency diverse array with logarithmical frequency increment, named the symmetrical-multilog-FDA, is used to obtain the direction-range-dependent DM signals that are normal at the desired locations while disordered at other locations. Based on the symmetrical-multilog-FDA, we derive the closed-form expression of baseband-weighted vector using the artificial-noise-aided zero-forcing approach. Compared with previous schemes, the proposed scheme can obtain a more fine-focusing nonperiodic dot-shaped secure area at the desired location. In addition, it can achieve a point-to-multipoint secure communication for multiple cooperative receivers at different locations.
