IEEE International Symposium on Information Theory
作者: Andreas Schenk Robert F.H. Fischer Lehrstuhl für Informationsübertragung Universität Erlangen Nürnberg Erlangen Germany
Power efficiency of noncoherent receivers for impulse-radio ultra-wideband (IR-UWB) transmission systems can significantly be improved, on the one hand, by employing multiple-symbol differential detection (MSDD), and,... 详细信息
