Une modulation directionnelle (DM) dépendante de la plage angulaire et invariante dans le temps de faible complexité, basée sur un réseau diversifié en fréquence modulé dans le temps (TM-FDA-DM), est proposée pour réaliser des communications de sécurité de couche physique point à point. Le principe de TM-FDA est élaboré et la méthode de synthèse vectorielle est utilisée pour réaliser la proposition, TM-FDA-DM, dans laquelle la normalisation et les matrices orthogonales sont conçues pour moduler respectivement les symboles de bande de base utiles et le bruit artificiel inséré. Étant donné que les deux matrices conçues sont des valeurs fixes invariantes dans le temps, ce qui évite le calcul en temps réel, le TM-FDA-DM proposé est beaucoup plus facile à mettre en œuvre que les DM invariants dans le temps basés sur le FDA linéaire conventionnel ou le FDA logarithmique, et il surpasse également les DM dépendant de la plage d'angle et invariant dans le temps qui utilise un algorithme génétique (GA) pour optimiser les déphaseurs sur l'interface radiofréquence (RF). De plus, une méthode de synthèse robuste pour TM-FDA-DM avec des estimations imparfaites d’angle et de portée est proposée en optimisant la matrice de normalisation. Les simulations démontrent que le TM-FDA-DM proposé présente des caractéristiques invariantes dans le temps et dépendantes de la plage d'angle, et que le TM-FDA-DM robuste proposé peut atteindre de meilleures performances BER que la méthode non robuste lorsque l'erreur de portée maximale est supérieure à 7 km. et l'erreur d'angle maximale est supérieure à 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°.
