Increasing capacity for wireless communication systems based on signal waveform collaboration
Published 2012-02-01“…A wireless communication technology based on signal waveform collaboration was proposed for resolving the conflict between limited spectrum resources and the rapidly growing service needs.The proposed technology employs linear frequency modulation (LFM) signals to transmit different users' information by utilizing the dual relationship between the energy concentration property of sinusoidal signals and that of LFM signals in the frequency and fractional domains,and the transmitted signals are superimposed on communication waveforms of the traditional sinusoidal carrier communication system on the same frequency band.At the receiver,frequency-and fractional-domain filters are applied to separate two kinds of users' signals.Moreover,the system model of the proposed technology is constructed,and theoretical analysis is also derived.The validity of the theoretical derivations is demonstrated via simulations.It has been shown that spectral efficiency can be effectively improved using signal waveform collaboration and transform-domain filtering.Theoretically,the proposed technology can achieve twice system capacity as large as that of the traditional sinusoidal carrier communication system.…”

Gain-aware caching scheme for information-centric networking
Published 2016-05-01“…The in-network caching system of information-centric networking had to deal with the popularity of huge number of content chunks and make efficient usage of storage resources.A content popularity based caching gain opti-mization model aimed to get maximum reduction of content retrieve cost was established,and a gain-aware caching scheme was proposed.By utilizing filtering effect of cache to request flow is scheme achieves caching cooperation and diversity potentially while maximizing caching gain of every single node.Bloom filter based sliding window strategy captures the content chunks with high caching gain according to request arrival interval and retrieval cost from the source.Analysis shows that the method can drastically reduce memory consumption caused by popularity monitoring.The simu-lation results illuminate that this scheme is well aware of content popularity based caching gain,and gets better band-width saving and cache hit ratio when content popularity is changing dynamically.…”
