Abstract:In order to save CP, improve the frequency band usage and improve the ISI situation, an algorithm is proposed that can realizes multi-carrier modulation and demodulation of signal transportation by fast wavelet packet transform. It adopts wavelet packet function as carriers which have the characteristic of good orthogonality and time-frequency limitation. It can be seen from both theoretical analysis and software simulation that multi-carrier modulation and demodulation technique based on wavelet packet transf… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
