Millimetre-wave (mmWave) communications have been regarded as a key technology for the next-generation cellular systems since the huge available bandwidth can potentially provide the rates of multiple gigabits per second. Conventional precoding and c

The Brazilian National Metrology Institute does not yet provide low current traceability. This prevents calibration of clinical dosimeters separated from its ionization chamber. To fill this gap the authors developed a prototype of a ramp generator t

Communications using the millimeter wave (mmWave) spectrum are a mainstream technology of the next generation systems due to its huge available bandwidth. However, the mmWave band will experience much more propagation loss than a low-frequency band.

We propose a hybrid precoder for downnlik mmWave massive MU-MIMO system designed through the maximization of the mutual information' upper bound. The methodology of a large number of the hybrid precoder proposed in the literature is focused on findin

In this paper, we propose an adaptive nonassisted distributed detection algorithm for sensor networks with fading communication channels and binary data exchange between nodes. Our proposal aims to achieve the solution of the network based only on th

The nonlinear nature of the quantization operation performed by the ADCs imposes great challenges to the systems employing coarse quantization. Systems operating in moderate to high SNR regimes experience a pronounced capacity loss and also impairmen
