Dual-Channel-Based Mobile Ad Hoc Network Routing Technique for Indoor Disaster Environment
IEEE Access, 2020 The existing network infrastructure may not work well in a disaster environment caused by a fire or an earthquake. Instead of relying on the existing infrastructure, communicating through a mobile ad hoc network (MANET) is recommended because MANET can ...

Ergodic Capacity Analysis of Amplify-and-Forward MIMO Dual-Hop Systems
, 2008 This paper presents an analytical characterization of the ergodic capacity of amplify-and-forward (AF) MIMO dual-hop relay channels, assuming that the channel state information is available at the destination terminal only.

Dual Channel S-Band Frequency Modulated Continuous Wave Through-Wall Radar Imaging
Sensors, 2018 This article deals with the development of a dual channel S-Band frequency-modulated continuous wave (FMCW) system for a through-the-wall imaging (TWRI) system. Most existing TWRI systems using FMCW were developed for synthetic aperture radar (SAR) which

Dual-channel OCT for Velocity Measurement in Microfluidic Channels
26th International Conference on Optical Fiber Sensors, 2018 A dual-beam Optical Coherence Tomography system has been developed, using a bespoke dual optical fibre, to simultaneously image microfluidic channel structures and measure high velocity flows (presently 250μm/s) from a single optical access point.
