Massive MIMO

, 2017
Com a chegada da quinta geração de comunicações móveis (5G) espera-se que os sistemas de comunicação sem fios possam oferecer novos e melhores serviços com ritmos de transmissão elevadíssimos. O aumento significativo do bit rate que se prevê com o incremento dos utilizadores e dos dispositivos a ligar a rede, a entrada da IoT e outas tecnologias, isto ...

From Compact MIMO to Massive MIMO

, 2022
We study information theoretic design of compact antenna arrays and nonlinear precoding for multiuser MIMO channels with coarsely quantized alphabets. For the RF front-end design, it is shown that a class of lossless multiport matching networks maximizes information rates at any antenna spacing.

The Relationship Between EMF Exposure and MIMO Systems, and the Exposure Advantages of Lowband Massive MIMO System

Telecom
With the advancement of mobile communications, technologies based on high-element-count antenna systems—such as massive Multiple Input Multiple Output (massive MIMO)—are playing an increasingly important role in enhancing network capacity.
