A Polarized Phase Shifting Keying/Quadrature Amplitude Modulation (PPSK/PQAM) scheme
in the wireless depolarized channel is proposed. Such scheme uses the carrier's …

In this paper, we consider the problem of spectrum sensing in cognitive radios by exploiting
Stokes subvector, which can completely describe energy and polarization information of the …

Ultra-dense deployment of small cell networks is widely regarded as a key role to meet the
increasing demand for huge capacity of wireless communication systems. Meanwhile …

In this work, a Semi-Blind Polarization Adaption (SBPA) technique that utilizes the sampled
primary signals and channel reciprocity is proposed for cognitive users. The proposed …

In this work, a joint polarization adaption and beamforming technique is proposed for
horizontal spectrum sharing for TD-LTE and FD-LTE users. The polarization and spatial …

This paper proposes a novel polarization-based underlay spectrum sharing scheme in
cognitive heterogeneous cellular network (CHCN). Distinguished from traditional spectrum …

Polarized spectrum sharing (PSS) exploits the spectrum opportunities in a polarized domain.
However, when it comes to wideband environments PSS is impaired by the frequency …

Cognitive heterogeneous cellular network (CHCN), comprised of small cells overlaid with
macrocells, is a promising topology to fulfill the explosive demand for high-data-rate …

In cognitive radios, the biggest challenge is spectrum sensing. It usually makes use of the
amplitude, frequency or space dimension of the received signal to differentiate signal from …
