A Simple Carrier Frequency Offset Synchronization Strategy for Multiple Relay Cooperative Diversity OFDM System
Cooperative Diversity Orthogonal Frequency Division Modulation (CD-OFDM) systems are very sensitive to synchronization errors. In CD-OFDM, synchronization is more complex because all cooperative nodes (CNs) have their own frequency oscillator and different channel path which results in different timing and carrier frequency offset (CFO) for each node. Consequently, each node has to be synchroni...
متن کاملCarrier Frequency Offset Estimation in Ofdm Systems
Orthogonal Frequency Division Multiplexing (OFDM) is multicarrier modulation scheme for combating channel impairments such as severe multipath fading and impulsive noise. However, the principal disadvantage of OFDM is that it is highly susceptible to carrier frequency offset (CFO). Carrier frequency offset occurs due to frequency discrepancies between transmitter and receiver and Doppler shift ...
متن کاملCarrier Frequency Offset Estimation for Orthogonal Frequency Division Multiplexing Systems
Carrier Frequency Offset Estimation for Orthogonal FrequencyDivision Multiplexing Systems Xiang Nian Zeng, Ph.D. Concordia University, 2008 Orthogonal frequency division multiplexing (OFDM) is an attractive modulation scheme used in wideband communications because it essentially transforms the frequency selective channel into a flat fading channel. Furthermore, the combination of multiple-input...
متن کاملA Cooperative Positioning Method for VANETs using DSRC Carrier Frequency Offset
Vehicular positioning in urban canyons or covered areas such as car parks is a challenging issue due to the limited availability or lack of Global Navigation Satellite System (GNSS) signals. Tackling this problem, the concept of Cooperative Positioning (CP) has recently emerged for positioning or positioning enhancement in Vehicular Ad-Hoc Networks (VANETs). In the literature, CP techniques are...
متن کاملCarrier Offset and Channel Estimation for Cooperative MIMO Sensor Networks
A cooperative MIMO network is considered with Ns sensors and a collector node with Mc antennas. In a practical implementation of this network, the sensor carriers have relative frequency offsets which must be estimated along with the MIMO channel. Generalized successive interference cancellation (GSIC) is proposed for this joint estimation problem. The primary operations in GSIC are correlation...
