We propose a flexible multi-frequency channel correlator upgrade for MUSER-I array. The upgrade correlator has a more flexible architecture to be extensible for signal receiving elements. It can process 1024 frequency channels in IF band and the correlation sensibility is improved by utilizing 4-bit quantization in pre-correlation as well. The enhanced multi-frequency channel processing capability...
Recent years have seen the proliferation in versatile mobile devices and application services that demand different data rates and latencies. Fixed channelization configuration in today’s wireless devices fail to be efficient in the presence of such dynamic demands. In this regard, fine-grained spectrum management designs have been advocated by the research community to embrace the heterogeneity in...
As the popularity of WebVR applications rises in recent years, a great disparity exists between the huge 3D content on servers and the limited cache capacity on clients. In order to alleviate server loading, peer-to-peer (P2P)-based 3D content distribution has been proposed recently. However, given the limited cache sizes at clients, how to maintain and replace the cache content effectively becomes...
