An Eigenvalue Based Carrier Frequency Offset Estimator for OFDM Systems

IEEE Wireless Communications Letters, 2013
Orthogonal frequency division multiplexing (OFDM) is sensitive to frequency synchronization errors. This letter proposes a novel data-aided carrier frequency offset (CFO) estimator. We show that the eigenvalues of the inter-carrier interference (ICI) coefficient matrix are the elements of a geometric series distributed on the unit circle of the complex

Intelligent Taxi Service System Based on Carrier-Cloud-Client

2015 IEEE 12th Intl Conf on Ubiquitous Intelligence and Computing and 2015 IEEE 12th Intl Conf on Autonomic and Trusted Computing and 2015 IEEE 15th Intl Conf on Scalable Computing and Communications and Its Associated Workshops (UIC-ATC-ScalCom), 2015
The development of cloud computing, big data and ubiquitous communication technologies bring a golden opportunity to traditional taxi service systems. In this paper, we propose an intelligent taxi service system based on Carrier-Cloud-Client framework of Internet of Vehicle (IOV) for the first time. Basically, the system employs an advanced intelligent

Systemic mRNA Delivery to the Lungs by Functional Polyester-based Carriers

Biomacromolecules, 2017
Messenger RNA (mRNA) has recently come into focus as an emerging therapeutic class with great potential for protein replacement therapy, cancer immunotherapy, regenerative medicine, vaccines, and gene editing. However, the lack of effective and safe delivery methods impedes the broad application of mRNA-based therapeutics.

Carrier Sensing for OFDMA-Based D2D Group-Casting Systems

IEEE Transactions on Vehicular Technology, 2017
Device-to-device (D2D) communications refer to direct communications between two or more devices without transferring data through the base station or other infrastructure. For synchronous D2D communication systems in most recent researches and development, orthogonal frequency-division multiple access (OFDMA) or single-carrier frequency-division ...

Efficient Structure-Based Carrier Offset Estimator for OFDM System

VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
In this paper, we proposed a closed form solution for blind Orthogonal Frequency Division Multiplexing (OFDM) Carrier Frequency Offset (CFO) estimation employing the Rank- Revealing QR triangular factorization Method (RRQR). The advantage of using the RRQR it gives precious information about numerical rank and efficiently separates the signal space ...

Resource Allocation in LTE-Based MIMO Systems with Carrier Aggregation

2016 IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016
Resource Allocation (RA) is one of the crucial elements in Long Term Evolution (LTE) networks, which has a tremendous impact on the network performance. However, complexity of the RA problem increases when both Carrier Aggregation (CA) and Multiple-Input Multiple-Output (MIMO) are enabled in the network. CA is a key functionality for LTE- Advanced (LTE-

An Autonomous GPS Carrier-Phased-Based System for Precision Navigation

2006 IEEE Intelligent Transportation Systems Conference, 2006
Precision navigation tasks have traditionally been carried out in the differential positioning mode. This is due mainly to the higher positioning accuracy obtained with the differential positioning mode compared to that of GPS point positioning. A major disadvantage of GPS differential positioning, however, is its dependency on the measurements or ...
