Device and method for determining channel equalization and reception data of receiver for packet communication
First Claim
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.

Abstract
Provided is an apparatus for equalizing a channel and determining reception data of a packet communication receiver. The apparatus includes: an input interface unit which receives a reception sample string of a packet having a midamble and location information of the midamble; a sample dividing unit which divides the reception sample string into a first sub sample string and a second sub string stream using the location information of the midamble; and a channel equalizing unit which performs channel equalization on the first sub sample string and the second sub sample string, respectively, using a channel equalizing algorithm of the channel equalizer.
