METHOD AND THE CORRESPONDING APPARATUS FOR DATA COMPRESSION, TRANSMISSION, RECEPTION AND DECOMPRESSION

摘要

A method and the corresponding apparatus for data compression, transmission, reception and decompression is provided, which achieves IQ data compression in lower complexity and smaller error, and achieves the transmission of IQ data compression factor by using less resource. The data compression method comprises the following steps: reading the data to be compressed; searching I data and Q data whose the absolute value is greatest, from a set of data to be compressed; determining effective bits number M of the I data whose the absolute value is greatest and effective number of bits N of the Q data whose the absolute value is greatest; according to effective bits number M and the compressed target bit wide number x, generating a first DAGC factor for compressing I data; according to effective bits number N and the compressed target bit wide number x, generating a second DAGC factor for compressing Q data; using the first DAGC factor to compress each I data of the data to be compressed; using the second DAGC factor to compress each Q data of the data to be compressed.
