Hardware distortions (HWD) render drastic effects on the performance of communication systems. They are recently proven to bear asymmetric signatures; and hence can be efficiently mitigated using improper Gaussian signaling (IGS), thanks to its additional design degrees of freedom. Discrete asymmetric signaling (AS) can practically realize the IGS by shaping the signals' geometry or probability. In this paper, we adopt the probabilistic shaping (PS) instead of uniform symbols to mitigate the… Expand

Impact of improper Gaussian signaling on hardware impaired systems
TLDR
This paper accurately model the hardware impairments (HWI) as improper Gaussian signaling (IGS) which can characterize the asymmetric characteristics of different HWI sources and quantifies the performance degradation in the absence of ideal transceivers and the gain reaped from adopting IGS scheme compared with PGS scheme.

TLDR
This paper accurately model the impact of aggregate hardware impairments (HWIs) in communication systems as improper Gaussian signals (IGS), which can describe the asymmetric characteristics of different HWI sources and proposes an adaptive scheme to switch between maximal IGS and PGS schemes under certain conditions to improve the system performance with least computational/optimization overhead.

Improper Signaling for SISO Two-User Interference Channels With Additive Asymmetric Hardware Distortion
TLDR
This paper investigates the rate benefits of IGS in a two-user interference channel (IC) with additive asymmetric HWD when interference is treated as noise and proposes two iterative algorithms to optimize the parameters of the improper transmit signals. Expand

The findings reveal that using IGS in single-user detection systems that suffer from both RSI and HWD can effectively mitigate the degradation in the achievable rate performance, especially at higher interference-to-noise ratio. Expand
Information-Theoretic Analysis of a Family of Improper Discrete Constellations
TLDR
A new family of improper constellations generated by widely linear processing of a square M-QAM (quadrature amplitude modulation) signal is proposed, parameterized by κ, the circularity coefficient and a phase ϕ to maximize the minimum Euclidean distance between points of the improper constellation, therefore minimizing the bit error rate.
