TL;DR: The IoT ecosystem is presented and how the combination of IoT and DA is enabling smart agriculture, and future trends and opportunities are provided which are categorized into technological innovations, application scenarios, business, and marketability.

TL;DR: An extensive survey on pilot contamination in massive MIMO systems is provided, and other possible sources of pilot contamination are identified, which include hardware impairment and non-reciprocal transceivers.

TL;DR: Non-orthogonal multiple access (NOMA) is investigated for aerial base station (BS) and results are presented for various environment settings to conclude NOMA manifesting better performance in terms of sum-rate, coverage, and energy efficiency.

TL;DR: This paper describes the different beamforming approaches in each network topology according to its design objective such as increasing the throughput, enhancing the energy transfer efficiency, and minimizing the total transmit power, with paying special attention to exploiting the physical layer security.

TL;DR: A survey on the research trends of distributed and collaborative beamforming in WSNs uncovered that majority of existing research can be broadly divided into four major research trends: beampattern analysis, power and lifetime optimization, synchronization, and finally, prototype design.
