Abstract Directional modulation is one of the hot topics in data security researches. To
fulfill the requirements of communication security in wireless environment with multiple
paths, this study takes into account the factors of reflections and antenna radiation pattern
for directional modulation. Unlike other previous works, a novel multiple-reflection
model, which is more realistic and complex than simplified two-ray reflection models, is
proposed based on two reflectors. Another focus is a quantum genetic algorithm applied
to optimize antenna excitation in a phased directional modulation antenna array. The
quantum approach has strengths in convergence speed and the globe searching ability for
the… More >
