Abstract
Provided is an OFDM receiver which extracts a time sync signal from a prefix having a symmetric structure. The OFDM receiver, according to exemplary embodiments of the present invention, generates the sync signal (e.g., start point) of a symbol by using only the MSB (e.g., sign bit) of the cyclic prefix of an OFDM symbol, reducing the overhead of a logic circuit for generating the sync signal of the symbol.
