1. A method performed by a receiving node in a wireless communication system, comprising:
receiving a signal from a transmitting node;
determining an energy metric by normalizing an average energy of the received signal;
identifying whether the energy metric exceeds a first threshold;
obtaining a plurality of decoding paths by decoding bits contained in the received signal based on identification that the energy metric exceeds the first threshold; and
identifying whether the decoding is successful based on a detection metric determined based on values representing path metrics of the plurality of the decoding paths,
wherein the detection metric is determined by dividing an absolute value of a difference between a maximum value among the path metrics of the plurality of the decoding paths and a minimum value among path metrics of decoding paths passing a cyclic redundancy check (CRC) check by an average value of the path metrics of the plurality of the decoding paths.
