Study on OFDM Symbol Timing Synchronization Algorithm
OFDM technology has become the core technology of the next generation mobile communication system because of the high bandwidth efficiency, the strong ability to resist inter-carrier interference and anti-channel interference. However, because OFDM system is a multicarrier modulation system, the system will be very sensitive to its synchronization errors. Synchronization estimation is an import...
متن کاملSynchronization of Symbol Timing in the OFDM Single-Frequency Networks
In this paper, we propose the method to estimate OFDM symbol timing in Single-Frequency Networks (SFN). For the efficient data transmission, the method employs redundant cyclic prefix (CP) instead of the train sequence and requires only a small proportion of CP not corrupted by inter-symbol interference (ISI). The proposed algorithm can estimate two points which indicate the beginning and end o...
متن کاملBlind symbol synchronization for direct detection optical OFDM using a reduced number of virtual subcarriers.
Symbol synchronization constitutes a major component in optical OFDM transceivers. In this paper, we propose reducing the complexity of a blind symbol synchronization technique for direct detection OFDM receivers based on virtual subcarriers by optimizing the number and location of the virtual subcarriers. Compared to the system design in our previous study, this new technique offers a reductio...
متن کاملReview on Comparison of Different OFDM Symbol Timing Synchronization Algorithms
Orthogonal Frequency Division Multiplexing (OFDM) is the key technology for 4G and 3GPP LTE systems due to its highly efficient bandwidth and multi carrier modulation. The benefit of using OFDM is that it avoids ISI (Inter Symbol Interference) and ICI (Inter carrier Interference) by using timing synchronization technique. For this the symbols must be in properly synchronized form. It also have ...
متن کاملRobust Symbol Timing Synchronization for OFDM Systems Using PN Sequence
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...
