Uma modulação direcional dependente de faixa de ângulo e invariante no tempo de baixa complexidade (DM) baseada em matriz diversificada de frequência modulada no tempo (TM-FDA-DM) é proposta para obter comunicações de segurança da camada física ponto a ponto. O princípio do TM-FDA é elaborado e o método de síntese vetorial é utilizado para concretizar a proposta, TM-FDA-DM, onde normalização e matrizes ortogonais são projetadas para modular os símbolos úteis da banda base e o ruído artificial inserido, respectivamente. Como as duas matrizes projetadas são valores fixos invariantes no tempo, o que evita o cálculo em tempo real, o TM-FDA-DM proposto é muito mais fácil de implementar do que os DMs invariantes no tempo baseados no FDA linear convencional ou no FDA logarítmico, e também supera o DM dependente da faixa de ângulo invariante no tempo que utiliza algoritmo genético (GA) para otimizar os deslocadores de fase no frontend de radiofrequência (RF). Além disso, um método de síntese robusto para TM-FDA-DM com estimativas imperfeitas de ângulo e alcance é proposto através da otimização da matriz de normalização. Simulações demonstram que o TM-FDA-DM proposto exibe características invariantes no tempo e dependentes do alcance do ângulo, e o TM-FDA-DM robusto proposto pode alcançar melhor desempenho de BER do que o método não robusto quando o erro máximo de alcance é maior que 7 km e o erro máximo do ângulo é maior que 4°.

Abstract: A low-complexity time-invariant angle-range dependent directional modulation (DM) based on time-modulated frequency diverse array (TM-FDA-DM) is proposed to achieve point-to-point physical layer security communications. The principle of TM-FDA is elaborated and the vector synthesis method is utilized to realize the proposal, TM-FDA-DM, where normalization and orthogonal matrices are designed to modulate the useful baseband symbols and inserted artificial noise, respectively. Since the two designed matrices are time-invariant fixed values, which avoid real-time calculation, the proposed TM-FDA-DM is much easier to implement than time-invariant DMs based on conventional linear FDA or logarithmical FDA, and it also outperforms the time-invariant angle-range dependent DM that utilizes genetic algorithm (GA) to optimize phase shifters on radio frequency (RF) frontend. Additionally, a robust synthesis method for TM-FDA-DM with imperfect angle and range estimations is proposed by optimizing normalization matrix. Simulations demonstrate that the proposed TM-FDA-DM exhibits time-invariant and angle-range dependent characteristics, and the proposed robust TM-FDA-DM can achieve better BER performance than the non-robust method when the maximum range error is larger than 7km and the maximum angle error is larger than 4°.
