METHOD AND DEVICE FOR DECOMPRESSING COMPRESSED SIGNAL AND WIDEBAND RECEIVING APPARATUS USING THE SAME

摘要

The present invention is a compressed signal restorer for restoring a compressed signal generated by synthesizing a local oscillation signal with the received signal amplified, a Fourier transform unit capable of converting a compressed signal from a time-based signal to a signal of a frequency board; A measurement matrix generation unit capable of generating a measurement matrix having a complex inverse matrix relationship with a matrix for the local oscillation signal; And a signal restoration unit capable of restoring a compressed signal converted to a frequency-based signal to an original signal by using the measurement matrix generated by the measurement matrix generation unit. Since the measurement matrix is generated by detecting the singular information and reflecting the detected singular information, it is possible to improve the performance of restoring the compressed signal.
