Modified modulation formats using time-varying phase functions
IEEE Transactions on Wireless Communications, 2006New modulation formats are presented that increase the transmission rate over that of conventional systems, without degrading the bit error rate (BER) and with minimal bandwidth variation. A time-varying function called an "extra phase variation function" (EPVF) is added to the discrete phase of conventional modulation formats such as M-PSK and QAM to ...

In oceanographic mapping, underwater exploration, and military reconnaissance scenarios, it is necessary to deploy multiple autonomous underwater vehicles (AUVs) to cooperatively fulfill some operational tasks. In the presence of uncertain dynamics, time-

Cooperative Target Tracking with Time-Varying Formation Radius
2015 European Control Conference (ECC), 2015This paper extends our previous results on cooperative target tracking of a moving ground vehicle using multiple unmanned aerial vehicles with constant 2D horizontal range to a time-varying horizontal range. An early-designed guidance law that orbits one UAV around the target is modified to handle time-varying horizontal range given by a prescribed ...

This brief is concerned with the time-varying formation problem for second-order networked multi-agent systems, which are subject to random communication delays and packet dropouts in the sensor-to-controller and controller-to-actuator channels of each ...

Controllability of Formations Over Directed Time-Varying Graphs
IEEE Transactions on Control of Network Systems, 2017In this paper, we investigate the controllability of a class of formation control systems. Given a directed graph, we assign an agent to each of its vertices and let the edges of the graph describe the information flow in the system. We relate the strongly connected components of this graph to the reachable set of the formation control system. Moreover,
