Low complexity Erasure Insertion in RS-Coded SFH Spread-Spectrum Communications with Partial-Band Interference and Nakagami-$m$ Fading

open access: yes, 2002
—In this paper we propose two novel low-complexity, low-delay erasure insertion schemes, namely, the output threshold test (OTT) and joint maximum output and ratio threshold Test (MO-RTT). The employment of the OTT and MO-RTT is beneficial in the context

Time-Hopping Multicarrier Code-Division Multiple-Access

open access: yes, 2006
A time-hopping multicarrier code-division multiple-access (TH/MC-CDMA) scheme is proposed and investigated. In the proposed TH/MC-CDMA each information symbol is transmitted by a number of time-domain pulses with each time-domain pulse modulating a ...

Bioengineered Interfaces for Peripheral Nerve Sensory Restoration

open access: yesAdvanced Materials, EarlyView.
Half of amputees abandon their prosthetics for lack of feeling. This review charts the full path from peripheral nerve injury to restored sensation, through surgical, regenerative, noninvasive, and implanted approaches, and shows how injury type and interface material properties determine which strategy can deliver naturalistic feedback, and why ...

Optical frequency-tunable Cs atomic clock with a 9.19GHz mode-hop-free fiber laser

open access: yesIEICE Electronics Express, 2010
We successfully realized a 1.5µm optical frequency-tunable Cs atomic clock by employing a mode-hop-free 9.19GHz mode-locked erbium fiber laser with an optical etalon in the cavity. We achieved independent control of the optical frequency and the repetition rate (microwave frequency) of the 9.19GHz optical pulse, in which the microwave frequency was ...

Cooperative Goniopolar and Anomalous Nernst Transverse Thermoelectricity in Kagome Magnets

open access: yesAdvanced Materials, EarlyView.
A cooperative transverse thermoelectric mechanism is realized in kagome magnets, where axis‐dependent goniopolar effects and Berry curvature‐driven anomalous Nernst coexist within the same energy window. In MgMn6Sn6, this intrinsic synergy yields a record room‐temperature transverse thermopower of 15.6 µV K−1, establishing a general strategy for high ...

Unified Performance Analysis of Dual-Hop Radio Frequency/Free Space Optical System

open access: yesWireless Personal Communications
Abstract In this paper, the performance of the dual-hop radio frequency/free space optical (RF/FSO) system based on the amplify-and-forward relaying scheme is analyzed. The RF link is modeled by Nakagami-m distribution for the multipath fading channel which is a generalized distribution.
