TL;DR: A unified closed-form expression, applicable to different binary modulation schemes, for the bit error rate of dual-branch selection diversity based systems undergoing independent but not necessarily identically distributed generalized-K fading is derived in terms of the extended generalized bivariate Meijer G-function.

TL;DR: This paper surveys the different rate optimization scenarios studied in the literature when PD-NOMA is combined with one or more of the candidate schemes and technologies for B5G networks including multiple-input-single-output (MISO), multiple- input-multiple- Output (MIMO), massive-MIMo), advanced antenna architectures, higher frequency millimeter-wave (mmWave) and terahertz (THz) communications.

TL;DR: The approach introduced in this paper can be used to well-approximate the distribution of the sum of independent generalized-K random variables by a gamma distribution; the need for such results arises in various emerging distributed communication technologies and systems such as coordinated multipoint transmission and reception schemes.

TL;DR: This paper provides a comprehensive overview of multi-user VLC systems discussing the recent advances on multi- user precoding, multiple access, resource allocation, and mobility management and possible directions for future research in this emerging topic.

TL;DR: An approximation of the generalized-K PDF by the familiar Gamma PDF is introduced, and the region-wise approximation obtained by the adjusted moment matching method is used to well-approximate the PDF of the sum of identically and independent generalized-k random variables.
