Proactive spectrum monitoring with spectrum monitoring data transmission in dynamic spectrum sharing network: Joint design of precoding and antenna selection

open access: yesIET Communications, 2021
A proactive spectrum monitoring and spectrum monitoring data (SMD) transmission coexistence system is investigated in dynamic spectrum sharing network, where a spectrum monitor (SM) aims to monitor the spectrum information from the electromagnetic signal

A high bit rate free space optics based ring topology having carrier‐less nodes

open access: yesIET Communications, 2021
A free space optics based ring topology that transmits full‐duplex data to four different nodes in the ring is proposed. The link is designed such that the four nodes do not require a local optical source to transmit the uplink data.

Fractional pilot reuse and max k‐cut based pilot decontamination scheme for multi‐cell TDD massive MIMO systems

open access: yesIET Communications, 2021
In multi‐cell massive multiple‐input multiple‐output (MIMO) cellular networks, pilot contamination (PC) caused by ineluctable pilot reuse severely restricts the system performance in the effectiveness and reliability of transmission.

Equipment selection heuristics for microwave fixed links

open access: yes, 2015
Microwave fixed links use highly standardized radio equipment and, in the radio equipment standard referenced in this paper, there is a choice between exactly two radio systems when the assigner wishes to resolve a specific data rate exactly: one using a

Blind detection of cyclostationary signals based on multi‐antenna beamforming technology

open access: yesIET Communications, 2021
Cyclostationary feature detection is one of the widely used spectrum sensing techniques. Its greatest advantage is that it can effectively separate the signal from the noise under the condition of a low signal‐noise ratio (SNR).
