DATA COMPRESSION APPARATUS

摘要

Provided is a data compression apparatus. The data compression apparatus includes a header information extraction extracting block header information on compressed data from I/Q data block generated by dividing data on a block basis, a block scaling unit generating an I/Q data scaling block by performing block scaling on the I/Q data block based on the block header information, and a compressed data generation unit generating compressed data by using a block header based on the block header information and the I/Q data scaling block.

1. A data compression apparatus comprising:
a data storage unit storing received in-phase (I) data and quadrature (Q) data, dividing and outputting each of stored I data and Q data on a block basis; a header information extraction unit extracting block header information by using a maximum value obtained from an I data block and Q data block generated by dividing the I data and Q data on the block basis and predetermined padding data; a block scaling unit generating an I data scaling block and Q data scaling block obtained by performing block-scaling on the I data block and Q data block based on the block header information; and a compressed data generation unit generating compressed data by using a block header based on the block header information, the I data scaling block, and the Q data scaling block.
