Reconfigurable Intelligent Surface: Design the Channel -- a New Opportunity for Future Wireless Networks
Miguel Dajer, Zhengxiang Ma, Leonard Piazzi +5
In this paper, we survey state-of-the-art research outcomes in the burgeoning field of reconfigurable intelligent surface (RIS) in view of its potential for significant performance…
Base Station Antenna Selection for Low-Resolution ADC Systems
Jinseok Choi, Junmo Sung, Narayan Prasad +3
This paper investigates antenna selection at a base station with large antenna arrays and low-resolution analog-to-digital converters. For downlink transmit antenna selection for n…
New equivalent model of quantizer with noisy input and its application for ADC resolution determination in an uplink MIMO receiver
Arkady Molev-Shteiman, Xiao-Feng Qi, Laurence Mailaender +2
When a quantizer input signal is the sum of the desired signal and input white noise, the quantization error is a function of total input signal. Our new equivalent model splits th…
Optimizing Beams and Bits: A Novel Approach for Massive MIMO Base-Station Design
Narayan Prasad, Xiao-Feng Qi, Alan Gatherer
We consider the problem of jointly optimizing ADC bit resolution and analog beamforming over a frequency-selective massive MIMO uplink. We build upon a popular model to incorporate…
Exploiting Dual Connectivity in Heterogeneous Cellular Networks
Narayan Prasad, Sampath Rangarajan
We consider network utility maximization problems over heterogeneous cellular networks (HetNets) that permit dual connectivity. Dual connectivity (DC) is a feature that targets eme…
Optimizing User Association and Activation Fractions in Heterogeneous Wireless Networks
Vaibhav Singh, Narayan Prasad, Mustafa Y. Arslan +1
We consider the problem of maximizing the alpha-fairness utility over the downlink of a heterogeneous wireless network (HetNet) by jointly optimizing the association of users to tr…
