A communication receiving device is provided. The communication receiving device includes a cross-correlation measuring circuit which receives an L-SIG (Legacy signal) symbol and a RL-SIG symbol to measure a cross-correlation degree therebetween, an accumulating circuit which accumulates a real part of a cross-correlation degree measurement value, a comparator which compares the accumulated L-SIG symbol and the RL-SIG symbol with a variable threshold value, and a threshold value calculator for calculating the threshold value.

Communication receiving device and method for operating the same

A receiver of a wireless communication system and method thereof include antennas configured to receive data, wherein the data comprises a preamble, a header, and a payload. The receiver also includes a synchronizer configured to perform time synchronization of the data received through corresponding paths of each antenna using corresponding preambles of the data. The receiver includes a header detector configured to detect a header from the data of each of the paths. A surviving path selector in the receiver is configured to select a signal of a surviving path from among the paths based on the header or the preamble. The receiver also includes combiner configured to combine the signal existing in the surviving path to demodulate the payload.
