Abstract: Disclosed are methods and apparatuses for compressing and decompressing data at a sample rate lower than a Nyquist sampling rate for the data. The data compression apparatus comprises a domain converting part performing a domain conversion on input data to generate domain-converted input data, and a data compression part generating compressed data by down-sampling the domain-converted input data at a sampling rate lower than a Nyquist sampling rate. Therefore, data to be transmitted can be compressed in a transmitting end by sampling the data at a sampling rate lower than a Nyquist sampling rate, and then the data can be reproduced in a receiving end. Therefore, a higher compression ratio can be achieved as compared with that of conventional technologies.
