A successful approach for designing a compact reconfigurable antenna system using a single active and two parasitic reactance-loaded dipoles is proposed. The switched parasitic antenna (SPA) operates at 2.6 GHz using PIN diode technology. It is designed to ...
Several studies have been done or have been started in order to extend the current aeronautical Space Based Augmentation System (SBAS) DO-229D Minimum Operational Performance Specification (MOPS) SBAS standard mainly defined by the Radio Technical ComiteeC ...
The development of efficient systems for precise attitude and position determination of airborne sensor platforms is having a huge impact in different remote sensing applications, resulting in higher productivity levels and lower exploitation costs. This t ...
In this paper, we consider an impulse-based ultrawideband (UWB) receiver and assess the performance of different multiple access and modulation schemes, including time-hopping pulse position modulation (TH-PPM), time-hopping binary phase shift keying (TH-B ...
With the introduction of a square wave sub-carrier modulation in the Galileo E1 BOC(1,1) open service signal, the autocorrelation function becomes more complex as compared to the GPS L1 C/A BPSK(1) signal. Indeed, the presence of two secondary side lobes i ...
