Digital precoding techniques have been widely applied in multiple-input multiple-output
(MIMO) systems to enhance spectral efficiency (SE) which is crucial in 5G New Radio (NR) …

This work reports the implementation of a multiband 5G new radio (NR) fiber-wireless (FiWi)
system, using analog radio over fiber (A-RoF) technology. Our approach employs a 12.5-km …

This paper deals with the evolution of downlink codebook based multiple-input multiple-
output (MIMO) within the third generation partnership project (3GPP) through release 15 to …

The next generation of mobile communication system will allow a plethora of new services
and use cases. By offering support for high throughput connections, low latency response …

We study the problem of providing channel state information (CSI) at the transmitter in multi-
user “massive” MIMO systems operating in frequency division duplexing (FDD). The …

Enhancing the throughput of multi-user (MU) massive multiple-input multiple-output (MIMO)
networks is one of the biggest promises that the fifth generation (5G) networks are expected …

The new applications enabled by the 5G new radio (NR) use cases require novel solutions
capable of supporting high end-user data rates at low latency. To meet these needs, it is …

Beamforming and precoding/combining are techniques aimed at processing multiantenna
signals at the transmitter and/or at the receiver of a wireless communication system. While …

To get channel state information (CSI) at a base station (BS), most of researches on massive
multiple-input multiple-output (MIMO) systems consider time division duplexing (TDD) to get …
