Robust Symbol Timing Synchronization for OFDM Systems Using PN Sequence
نویسندگان
چکیده
Abstract—This paper presents the symbol timing synchronization for OFDM receivers using PN sequence of values 1 or -1. The proposed design preamble is based on the correlation property of Pseudo Noise (PN) codes. Simulation results show that the proposed scheme is more robust to multipath fading channel than the conventional PN-based Park method, particularly at low SNR. It helps in setting the high threshold value in timing metric estimator.

Robust Signal Detection and Timing Synchronization Algorithms for OFDM Based Wireless Systems
In this paper, we propose robust and efficient signal detection and symbol timing synchronization schemes applicable to preamble based wireless systems such as WLAN and WMAN-OFDM. The signal detection algorithm is based on detecting the increase in energy at the beginning of the preamble. For symbol timing synchronization, instead of using conventional normalized timing metric, a new algorithm ...
متن کاملRobust Synchronization to Frequency Selective Fading Channel in OFDM Systems
The synchronization is one of the most important issues in the OFDM systems. Although the cyclic prefix has widely been used for symbol synchronization, it may not provide performance robust to the multi-cell environment. Therefore, the training symbol method is usually employed in multi-cell environment. Although the use of matched filter can provide best performance, it may have a problem of ...
