    摘要： 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.

    摘要： A method and a target node for preventing collisions between networks communicating based on a carrier sense multiple access/collision avoidance (CSMA/CA) scheme, are provided. The method includes synchronizing an object network with a neighboring network. The method further includes allocating, to the object network, a slot index based on a number of the networks, and a contention window (CW) size. The method further includes setting, for the object network, a back-off counter value based on the CW size. The method further includes reducing the back-off counter value based on a channel state of the object network, and the slot index. The method further includes transmitting data related to the neighboring network based on the back-off counter value.
