OFDM Frequency Offset Estimator Using PN Sequences and Its Improvement
نویسندگان
چکیده
In this paper, we proposed two new frequency synchronization methods for orthogonal frequency division multiplexing (OFDM) system. They have large estimation range and acceptability precision in Rayleigh channel. One of the methods will not waste the system bandwidth because the training sequence is superimposed on the data of OFDM symbol. The performance of the two methods is better than that of the method proposed by Tufvesson.

Carrier frequency offset estimation method for 2 × 1 MISO TDS-OFDM systems
In time-domain synchronous (TDS)-orthogonal frequency division multiplexing (OFDM) systems, a pseudo noise (PN) sequence is inserted instead of the cyclic prefix. The PN sequence is used not only as a guard interval but also as a training sequence for channel estimation and synchronization in the time domain. Recently, research studies on 2 × 1 multi input-single output (MISO) TDS-OFDM systems ...
متن کاملSimplified Frequency Offset Estimation in MIMO OFDM Systems
This paper addresses a simplified frequency offset estimator for multiple-input–multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems over frequency-selective fading channels. By exploiting the good correlation property of the training sequences, which are constructed from the Chu sequence, carrier frequency offset (CFO) estimation is obtained through factor decomposi...

Orthogonal Frequency Division Multiplexing (OFDM) plays an important role in the implementation of high data rate communication. In this thesis, the problems of data detection and channel and carrier frequency offset estimation in OFDM systems are studied. Multi-symbol non-coherent data detection is studied which performs data detection by processing multiple symbols without the knowledge of th...
متن کاملA Novel FFT-Based Frequency Offset Estimator for OFDM Systems
This paper proposes a novel frequency offset (FO) estimator for orthogonal frequency division multiplexing. Simplicity is most significant feature of this algorithm and can be repeated to achieve acceptable accuracy. Also fractional and integer part of FO is estimated jointly with use of the same algorithm. To do so, instead of using conventional algorithms that usually use correlation function...

In this paper a frequency offset estimation technique for Wireless Local Area and Wireless Metropolitan Area Networks is presented. For frequency offset estimation, we have applied a low-complexity frequency offset estimator for simple AWGN channels to fading channels for MIMO-OFDM systems. Simulation results have shown that the performance of the proposed estimator is better than the low compl...
