We study the spectral efficiency (SE) of a mixed-analog-to-digital converter (ADC) massive
multiple-input multiple-output (MIMO) system in which K single-antenna users communicate …

This paper concentrates on cell-free massive multiple-input and multiple-output (MIMO)
network with variable-resolution analog-to-digital converters (ADCs). In such an architecture …

Massive connectivity is a key requirement for the Internet of Things (IoT). In practice, the
network should be capable of accommodating thousands of devices and meeting their traffic …

We examine the uplink spectral efficiency of a massive MIMO base station employing a one-
bit Sigma-Delta (ΣΔ) sampling scheme implemented in the spatial rather than the temporal …

Increasing access to telecommunication services in rural parts of the world has the potential
to alleviate the digital divide felt by the people of these regions. Recently, both public and …

This paper aims to maximize the energy efficiency of a downlink cloud radio access network
(C-RAN). Here, data is transferred from a baseband unit in the core network to several …

In the recently proposed cell-free massive multiple-input and multiple-output (MIMO)
networks, the capacity of fronthaul links connecting all access points (APs) and a central …

This paper analyzes the outage probability for the uplink of multi-user massive multi-input-
multi-output systems with a mixed analog-to-digital converter (ADC) architecture, in which …

In a cell-free cloud radio access network (C-RAN) architecture, uplink channel estimation is
carried out by a centralized baseband processing unit (BBU) connected to distributed …

In this paper, we analyze the performance of uplink massive multiple‐input–multiple‐output
(MIMO) systems with variable‐resolution analog‐to‐digital converters (ADCs), ie, each …
