A Precoding and Power Control Scheme for SAR Reduction in Indoor MIMO Multicarrier Systems
Autor: Pat Chambers, Tim W. C. Brown
Publikováno v: IEEE Access, Vol 10, Pp 32301-32314 (2022)
In this work, a novel strategy for lowering the uplink user exposure index (EI) is described for an indoor narrowband use-case. This metric measures the long term exposure to electromagnetic radiation a user receives from a device operating in the up

A Statistical Knowledge Autocorrelation-Based Algorithm for Spectrum Sensing of OFDM Signals in Channels With Frequency Offset
Autor: Mathini Sellathurai, Pat Chambers
Publikováno v: IEEE Transactions on Vehicular Technology. 68:368-378
This paper presents a novel autocorrelation-based algorithm that uses statistical knowledge to detect orthogonal frequency division multiplexing signals in channels where frequency offset is present. The algorithm may be viewed as a significant impro

Tradeoffs in Detection and Localisation Performance for Mobile Sensor Scanning Strategies
Autor: Mathini Sellathurai, Pat Chambers, John Thompson, Loukianos Spyrou
Publikováno v: 2019 Sensor Signal Processing for Defence Conference (SSPD).
Wireless sensor networks enjoy many advantages over wired networks due to their ability to be deployed easily and flexibly in many scenarios. However, they suffer from the drawback that the environment may be unknown and hence the sensor network cann

Adaptive Bayesian Channel Estimation for Millimeter-Wave MIMO Systems with Hybrid Architecture
Autor: Rongrong Qian, Pat Chambers, Tharmalingam Ratnarajah, Mathini Sellathurai
Publikováno v: ACSSC
The hybrid multiple-input-multiple-output (MIMO) transceiver architecture is a promising solution to reducing hardware and power cost at millimeter-wave (mmWave) frequencies. However, channel estimation is a major issue for the deployment such system
