Effect of the cyclic prefix on the timing synchronization method in ACO-OFDM systems
Recently, a new timing synchronization method for optical wireless systems using asymmetrically clipped optical OFDM (ACO-OFDM) has been proposed. The synchronization method makes use of a novel training symbol and its autocorrelation properties for timing offset estimation via a timing metric. In this paper, we will discuss the effect of the length of cyclic prefix (CP) on the detection of the...
متن کاملOn Synchronization in OFDM Systems Using the Cyclic Prefix
In this paper, we present a data-based method for simultaneous Maximum Likelihood (ML) symbol timing and carrier-frequency offset estimation in Orthogonal frequency-division multiplexing (OFDM) systems. The cyclic extension, a guardspace preceding OFDM frames, is of decisive importance for this method. It is shown that the redundancy introduced by this cyclic extension allows the estimation to ...
متن کاملStudy 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 کاملOFDM Narrowband Interference Estimation Using Cyclic Prefix Based Algorithm
OFDM systems experience BER degradation in the presence of narrowband interference (NBI). We propose a novel NBI cancellation algorithm for a wideband OFDM receiver. Modelling the NBI as a single-tone sinusoid, subspace-based (SB) methods can be used to estimate it. However, direct application of SB methods to the received signal yields poor results except when the system is operating at very l...
متن کاملTiming and Frequency Synchronization in OFDM Systems Using the Cyclic Prefix
Abstract – We present a method for the joint estimation of timing and carrier-frequency offset in Orthogonal frequency-division multiplexing (OFDM) systems. We show that it is possible to generate these estimates without the use of pilots, by exploiting the cyclic prefix of OFDM frames. We derive the joint likelihood function of the offsetparameters given the received data. The performance of t...
