Rate matching apparatus and rate matching method thereof

A rate matching method comprising:

• removing dummy bits of interleaved code blocks;
• dividing code blocks with the dummy bits removed into systematic data and parity data, and storing the divided data in parallel;
• and
• outputting the stored data in parallel,
• wherein the outputting of the stored data comprises outputting data by using an output parameter for output of data based on removal of the dummy bit.

A rate matching method comprising:

• interleaving code blocks;
• removing dummy bits of the interleaved code blocks;
• collecting code blocks with the dummy bits removed, by bit units;
• dividing the collected data bits into systematic data and parity data to store the divided data in parallel;
• and
• outputting in parallel a plurality of data bits which are selected from the stored systematic data and parity data,
• wherein the outputting of data bits comprises calculating an output parameter on the basis of the systematic data and parity data with the dummy bits removed, and outputting the selected data bits in parallel according to the output parameter.
