摘要:For a cognitive radio network (CRN) in which a set of secondary users (SUs) competes for a limited number of channels (spectrum resources) belonging to primary users (PUs), the channel allocation is a challenge and dominates the throughput and congestion of the network. In this p...

摘要:The suppression of electromagnetic interferences (EMIs) caused by the out-of-band operation is required for broadband antennas. To achieve this purpose, a compact broadband printed slot antenna with build-in filters for band notching is presented. The filters, including I-shaped ...

摘要:Detailed analysis of tree canopy interaction with incident radiowaves has mainly been limited to remote sensing for the purpose of forest classification among many other applications. This represents a monostatic configuration, unlike the case of communication links, which are bi...

摘要:Through-the-Wall Radar Imaging (TWRI) could be performed by beamforming of the signals from an array of ultrawideband (UWB) antennas. Preferably the imaging is done in 3-D so that both the position and the height of the target be revealed. This is possible with planar array ...

摘要:In this paper, a circularly polarized U-slot half-mode substrate integrated waveguide (HMSIW) antenna is proposed. It is based on a combination of U-shaped slot etched in the HMSIW top wall and a shorting via placed between the area bounded by the slot and the HMSIW bottom wall. ...

摘要:In this paper, we evaluate probability of non-zero secrecy capacity of multi-hop relay networks over Nakagami-m fading channels in presence of hardware impairments. In the considered protocol, a source attempts to transmit its data to a destination by using multi-hop randomize-an...
