Journal ArticleDOI
Channel, Phase Noise, and Frequency Offset in OFDM Systems: Joint Estimation, Data Detection, and Hybrid Cramér-Rao Lower Bound
TL;DR: An expectation conditional maximization (ECM) based algorithm for joint estimation of channel, PHN, and CFO in OFDM systems and an iterative receiver based on an extended Kalman filter for joint data detection and PHN tracking are proposed.
Journal ArticleDOI
Multi-Relay Communications in the Presence of Phase Noise and Carrier Frequency Offsets
TL;DR: An iterative pilot-aided algorithm based on the expectation conditional maximization for joint estimation of multipath channels, Wiener PHNs, and CFOs in decode-and-forward-based multi-relay orthogonal frequency division multiplexing systems is proposed.
Proceedings ArticleDOI
An efficient unequal error protection scheme for 3-D video transmission
TL;DR: Experimental results show that the proposed schemes significantly achieve high video quality at different signal-to-noise ratios (SNRs) in the wireless channel with the lowest possible bandwidth and system complexity compared to the direct transmission schemes.
Journal ArticleDOI
Crack Monitoring System for Soft Rock Mining Conveyor Belt Using UHF RFID Sensors
TL;DR: In this article, a robust and low-cost passive ultra-high-frequency (UHF)-based radio frequency identification (RFID) crack sensing system was proposed, which allows the processing and detection of the presence of crack from the sensors' data in real time.
Proceedings ArticleDOI
Joint channel, phase noise, and carrier frequency offset estimation in cooperative OFDM systems
TL;DR: An iterative pilot-aided algorithm based on expectation conditional maximization (ECM) for joint estimation of multipath channels, Wiener PHNs, and CFOs in amplify-and-forward (AF) based cooperative orthogonal frequency division multiplexing (OFDM) system is proposed.
