Synchronization detection apparatus and method based on orthogonal frequency division multiplexing
An orthogonal frequency division multiplexing (OFDM)-based synchronization detection apparatus including a 2n level quantizing unit quantizing received data samples into levels of 2n, where n is an integer greater than or equal to zero (0), and a delaying unit delaying the data samples quantized through the 2n level quantizing unit by a predetermined number of clocks and outputting data indicative thereof. A shifting unit shifts the output data samples of the 2n level quantizing unit by an amount corresponding to an exponent of the output data of the delaying unit and a peak detecting unit detects a peak value from sums of outputs from the shifting unit.
