1. A method for equalizing a channel and determining reception data of a packet communication receiver, the method comprising:

  • receiving a reception sample string of a packet having a midamble and location information of the midamble;

    dividing the reception sample string into a first sub sample string and a second sub sample string using the location information of the midamble; and

    performing channel equalization on the first sub sample string and the second sub sample string, respectively, using a channel equalizing algorithm of a channel equalizer,wherein in the first sub sample string, a first symbol string is arranged in a first order of data 1 and the midamble and in the second sub sample string, a second symbol string is arranged in a second order of the midamble and data 2,wherein the performing of the channel equalization includes;

    rearranging the first order of the first sub sample string in reverse order to change arrangement of the first symbol string in a third order of a reversely arranged midamble and reversely arranged data 1;

    training a filter coefficient of the channel equalizer using a reversely arranged reference midamble symbol string as a training signal; and

    performing the channel equalization on the first sub sample string reversely arranged through the filter coefficient using the first sub sample string reversely arranged as an input reception signal of the channel equalizing algorithm of the channel equalizer.
