Learning to Select for Mimo Radar Based on Hybrid Analog-Digital Beamforming

ICASSP 2021accepted

In this paper, we propose an energy-efficient radar beampattern design framework for Millimeter Wave (mmWave) massive multi-input multi-output (mMIMO) systems, equipped with a hybrid analog-digital (HAD) beamforming structure. Aiming to reduce the power consumption and hardware cost of the mMIMO sys…

Q-Learning Based Predictive Relay Selection for Optimal Relay Beamforming

ICASSP 2020accepted

Wireless Autonomous Networks are expected to support communication between a source and a receiver, by constantly self-adapting to changes in their communication environment. This paper considers a scenario of relay beamforming, in which relays collaboratively retransmit the source signal so that th…

Adaptive margin slack minimization in RKHS for classification

ICASSP 2016accepted

In this paper, we design a novel regularized empirical risk minimization technique for classification called Adaptive Margin Slack Minimization (AMSM). The proposed method is based on minimizing a regularized upper bound of the misclassification error. Compared to the cost function of the classical…
