摘要： Provided are a decoding apparatus, a decoding method and a receiving apparatus for decoding in a system supporting an OFDM/OFDMA scheme. The decoding method includes the steps of: receiving phase-modulated signal; performing subcarrier demodulation on the received signal and generating correlation metrics; generating decoding metrics using the correlation metrics; and determining a payload using the largest metric of the decoding metrics and at least one of an average metric and the second largest metric of the decoding metrics. The decoding apparatus includes: a receiving buffer for buffering received phase-modulated signal; a likelihood metric generator for generating decoding metrics corresponding to likelihoods of the received signal buffered in the receiving buffer being determined as respective potential payload values; a mean calculator for calculating an average metric; and a payload determiner for determining a payload using the largest metric of the decoding metrics and at least one of an average metric and the second largest metric of the decoding metrics.
