In this paper, a novel frequency-hopping sequence with lower probability of detection is proposed for covert communication systems. By formulating and solving a constrained optimization problem, a probability vector aiming for covert communication is obtained in the presence of interference. The proposed frequency-hopping sequence chooses channels based on the probabilities, which can achieve the...
We study constrained optimization of two-dwell serial acquisition schemes in this letter. A noncoherent detector with full-period correlation (FPC) is investigated. The mathematical problem is to minimize a cost function (the mean acquisition time) depending on four parameters (two dwell durations and two thresholds) with two constraints (the false alarm probability and the miss detection probability),...
