The wireless communication serves the efficient information among two or more points wirelessly. Antenna is the main component in the communication, which radiates and receives the radio waves or in broad way. The antenna also plays a role of impedance matching device, which performs the matching of impedances like free-space & transmitter and receiver impedances at receiver end. The antennas c...

The performance and capabilities of a bistatic spaceborne synthetic aperture radar (SAR) are analyzed, where the transmitter and receiver are in different orbits. Such a configuration may be optimized for a broad range of applications like frequent monitoring, wide swath imaging, single-pass crosstrack interferometry, along-track interferometry, resolution enhancement or radar tomography.

In a multi-hop cooperative communication scenario, where a transmitter can transmit a packet directly to the receiver or indirectly through a relay, there is an inherent trade-off between energy and delay. While it may consume more energy to transmit a packet directly to the receiver than transmitting through a relay, the transmission through relay incurs more delay. We consider the MAC layer o...

Most studies of reflecting intelligent surfaces (RISs)-assisted visible light communication (VLC) systems have focused on the integration RISs in channel between transmitter-receiver pair to combat line-of-sight (LoS) blockage issue and enhance corresponding achievable data rate. Some recent efforts investigated liquid crystal (LC)-RIS VLC receiver also improve To jointly benefit from previousl...

In recent years, several emerging technologies in modern radar system design are attracting the attention of radar researchers and practitioners alike, noteworthy among which are multiple-input multiple-output (MIMO), ultra wideband (UWB) and joint communication-radar technologies. This thesis, in particular focuses upon a cognitive approach to design these modern radars. In the existing litera...

Bistatic synthetic aperture radar (BiSAR), operates with separate transmitter and receiver that are mounted on different platforms (Cherniakov & Nezlin, 2007), will play a great role in future radar applications (Krieger & Moreira, 2006). BiSAR configuration can bring many benefits in comparison with monostatic systems, such as the exploitation of additional information contained in the bistati...

A joint communication jamming waveform is proposed in this study based on the FBMC- chirp. To increase number of false targets a single pulse period, chirp signal modulated to different subcarrier groups. Since subcarriers FBMC-OQAM are orthogonal, signals naturally orthogonal. This allows transmitter and receiver be separated achieve multiple target jamming, allowing CFAR threshold raised by a...
