Modulasi arah bergantung (DM) bergantung kepada julat masa invarian masa berdasarkan tatasusunan pelbagai frekuensi termodulat masa (TM-FDA-DM) dicadangkan untuk mencapai komunikasi keselamatan lapisan fizikal titik ke titik. Prinsip TM-FDA dihuraikan dan kaedah sintesis vektor digunakan untuk merealisasikan cadangan, TM-FDA-DM, di mana normalisasi dan matriks ortogon direka untuk memodulasi simbol jalur asas yang berguna dan bunyi buatan yang dimasukkan, masing-masing. Memandangkan dua matriks yang direka bentuk ialah nilai tetap invarian masa, yang mengelakkan pengiraan masa nyata, TM-FDA-DM yang dicadangkan adalah lebih mudah untuk dilaksanakan berbanding DM invarian masa berdasarkan FDA linear konvensional atau FDA logaritma, dan ia juga mengatasi prestasi DM bergantung julat sudut invarian masa yang menggunakan algoritma genetik (GA) untuk mengoptimumkan pengalih fasa pada bahagian hadapan frekuensi radio (RF). Selain itu, kaedah sintesis yang teguh untuk TM-FDA-DM dengan sudut tidak sempurna dan anggaran julat dicadangkan dengan mengoptimumkan matriks normalisasi. Simulasi menunjukkan bahawa TM-FDA-DM yang dicadangkan mempamerkan ciri-ciri bergantung kepada invarian masa dan julat sudut, dan TM-FDA-DM yang teguh yang dicadangkan boleh mencapai prestasi BER yang lebih baik daripada kaedah tidak teguh apabila ralat julat maksimum lebih besar daripada 7km dan ralat sudut maksimum adalah lebih besar daripada 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°.
