The present invention provides an HARQ signal processing device for optimizing a data compression level, and a processing method thereof. The HARQ signal processing device of the present invention includes: a combiner which receives a log likelihood ratio (LLR) signal, determines whether the LLR signal is a new or retransmitted signal, and generates a composite signal by combining the LLR signal with a related signal received and previously stored when the LLR signal is the retransmitted signal; a compression level decision unit which calculates a first compression level based on quality of a received signal, calculates a second compression level based on available memory size, and decides a final compression level according to the first compression level and the second compression level; a compressor which compresses the LLR signal according to the final compression level; an HARQ memory that stores the compressed signal; and a decompressor which decompresses a signal read from the HARQ memory. |
