TLDR
In this article, a simple autocorrelation model for shadow fading in mobile radio channels is proposed, which is fitted to both large cells and microcells, and results show that the model fit is good for large to medium cells.Abstract:

Variable-rate variable-power MQAM for fading channels
Andrea Goldsmith,Soon-Ghee Chua +1 more
TL;DR: There is a constant power gap between the spectral efficiency of the proposed technique and the channel capacity, and this gap is a simple function of the required bit-error rate (BER).

TL;DR: The state-of-the-art survey of cooperative sensing is provided to address the issues of cooperation method, cooperative gain, and cooperation overhead.
Proceedings ArticleDOI
Cooperative Sensing among Cognitive Radios
TL;DR: This work proposes light-weight cooperation in sensing based on hard decisions to mitigate the sensitivity requirements on individual radios and shows that the "link budget" that system designers have to reserve for fading is a significant function of the required probability of detection.

Cell-Free Massive MIMO Versus Small Cells
TL;DR: In this paper, the authors proposed a max-min power control algorithm to ensure uniformly good service throughout the area of coverage in a cell-free massive MIMO system, where each user is served by a dedicated access point.
