In this paper, a new transmission scheme, signal space cognitive cooperation, is introduced
by applying the idea of signal space diversity in an underlay spectrum sharing decode-and …

Circular constellations have been widely studied for wireless communication systems, as
they have a lower peak-to-average power ratio (PAPR) than their rectangular counterparts …

This work focuses on the interplay between rotation angle, transmit power, fading severity,
and noise impairment severity in signal space diversity-based three time-slot decode-and …

A method, network node and user equipment are provided. In one or more embodiments, a
first user equipment, UE, configured to communicate with a second UE for performing non …

In this work, signal space diversity (SSD) method is exploited for a simple two-way relay
channel (TWRC) with two end users mutually exchanging information. In order to ensure …

The α− κ− μ fading channel is a generalized fading model that incorporates the nonlinearity
and nonhomogeneous scattering behavior of the propagation medium. In this paper, we …
