Frequency Offset Correction for OFDM Systems
نویسندگان
چکیده
In this paper, we propose a robust method to estimate carrier frequency offset (CFO) for orthogonal frequency division multiplexing (OFDM) systems. A training symbol with two identical halves is employed to measure the fractional part of the CFO. While the integral part is estimated by using a novel noise subspace based metric. Simulation results demonstrate that the proposed method can achieve an estimation range equal to the whole bandwidth of the OFDM signal. Copyright © 2013 IFSA.

A Low Complexity Forward Error Correction for PAPR reduction in OFDM Systems
In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mappe...
متن کاملResidual frequency offset correction for coherently modulated OFDM systems in wireless communication
Abstract—Orthogonal Frequency Division Multiplex (OFDM) systems are very sensitive to frequency offset caused by tuning oscillator instabilities and Doppler shifts induced by the channel. The Schmidl and Cox Algorithm (SCA) is quite robust in estimating the frequency offset for systems with large OFDM symbol lengths. It uses two OFDM symbols for training with the first one having two identical ...

Orthogonal Frequency Division Multiplexing (OFDM) is a promising research area in Wireless Communication for high data rates. The Multiple Input-Multiple Output (MIMO) technology when incorporated with the OFDM system promise a significant boost in the performance. But, the MIMOOFDM systems are very sensitive to Carrier Frequency Offset (CFO) as it deteriorates the system performance with the r...
متن کاملICI Performance Analysis for All Phase OFDM Systems
Orthogonal frequency division multiplexing (OFDM) is a strong candidate for the next generation wireless communication. But the frequency offset between the local oscillators at the transmitter and receiver causes a single frequency offset in the signal, while a time-varying channel can cause a spread of frequency offsets known as the Doppler spread. Frequency offsets ruin the orthogonal of OFD...
متن کاملIterative symbol offset correction algorithm for coherently modulated OFDM systems in wireless communication
Otrthogonal Frequency Division Multiplex (OFDM) system performance remains acceptable under timing synchronisation errors as long as the start of each symbol is determined to lie within a certain length into the Cyclie Prefix (CP). The Schmidl and Cox Algorithm (SCA) is quite robust in estimating the timing and frequency offset synchronisation for systems with large OFDM symbol lengths. It uses...
