Abstract
A receiving apparatus and receiving method employ a digital multi-carrier transmission technique utilizing a real coefficient wavelet filter bank in digital demodulation. The receiving apparatus may include a memory configured to store received waveform data corresponding to 2K symbols or more and a wavelet transformer configured to perform a wavelet transform based on the received waveform data stored in the memory, where K is an overlapping coefficient of a wavelet filter bank utilizing extended lapped transform (ELT).
