We propose a fully distributed approach to endow robots in a swarm with awareness of their relative position with respect to the rest of the swarm. Such spatial awareness can be used to support spatially differentiated task allocation or for pattern format ...
In this paper, we design a multiuser two-way relay system using space division multiple access (SDMA) communications and devise an optimal scheduling method that maximizes the sum rate while ensuring fairness among users. To reduce the computational load a ...
In this paper, multiple-input multiple-output (MIMO) relay transceiver processing is proposed for multiuser two-way relay communications. The relay processing is optimized based on both zero-forcing (ZF) and minimum mean-square-error (MMSE) criteria under ...
Numerous mobile applications and services require that devices are aware of their location. Global Navigation Satellite Systems (GNSS) are the predominant enabling technology. But in order to deliver continuous and accurate location information provided by ...
Since the dawn of the Space Age, over six thousand satellites have been launched into Earth orbit. The function of determining the orientation of a satellite in orbit, so that it can point its antennas and instruments in the required direction is known as ...
One of the most promising bands for long-range radiocommunications is the Ka-band (25-40 GHz). This is due to the existence of a natural radio transmission window around 30 GHz. Both terrestrial and satellite transmission systems are planned on this freque ...
The present thesis deals with the electromagnetic modeling, design and practical implementation of a planar antenna for the reception of satellite broadcasting services from user terminals on board automotive platforms. This antenna is intended to address ...
This communication presents a review of the developments carried out towards the electromagnetic modeling, design and practical implementation of the basic building block of a planar antenna for the reception of Ku-band satellite broadcasting services from ...
In this letter, a compact single-layer, single-feed, dual-frequency microstrip antenna with a high frequency ratio is proposed. This antenna has a broadside and symmetrical radiation patterns suitable for space-borne applications. The prototype was fabrica ...
