Abstract
In orthogonal frequency division multiplexing
(OFDM) systems, symbol synchronization is a critical step for
successful data transmission. While this task is done in most
current systems by using training symbols, a few studies have
been dedicated to solving the problem blindly, that is, where
training symbols are not available. Blind symbol synchronization
problem is especially important in many blind channel estimation
algorithms in the literature which assume that OFDM symbol
synchronization is perfect. In this paper, a broader version of the
blind symbol synchronization problem is studied, namely, blind
block synchronization in cyclic-prefix (CP) systems. The proposed
algorithm for this broader problem covers the blind symbol
synchronization problem in OFDM systems. Unlike previously
reported algorithms which are based on obtaining sufficient
statistics of received samples, the proposed algorithm is capable
of identifying the correct block boundaries using much less
received data in absence of noise. Simulation results of the
proposed algorithm not only verify the declared property but also
demonstrate improvement in accuracy of symbol synchronization
over previously reported algorithms in presence of noise.
