In this paper, we deal with the small-scale spectrum aggregation, where a set of even very narrow and disjoint frequency bands closely located on the frequency axis can be utilized simultaneously. Contrarily to our previous work on that subject, we concentrate on the multiuser scenario in which the 5G system tries to share the spectrum interleaved by multiple narrowband signals realized in the protected...
The synchronization at the Non-Contiguous Orthogonal Frequency Division Multiplexing (NC-OFDM) based Cognitive Radio (CR) receiver is a challenge. High-power interference from spatially- and spectrally-neighboring wireless systems may disrupt CR synchronization. In the same time, spectrum shaping techniques might be applied in the CR transmitter to reduce interference generated to other wireless systems...
In this paper the Multiple-Input-Single-Output (MISO) antenna system is considered, where a set of wearable antennas is deployed on various locations on the body, in order to enhance the connection reliability with the distant cellular-network receiver. Two body dynamics in a street scenario, i.e., run straight and run in loop are analysed. First of all, using the Geometrically Based Stochastical...
