54th Annual IEEE Global Telecommunications Conference (GLOBECOM)
作者: Ndih, Eugene David Ngangue Cherkaoui, Soumaya Univ Sherbrooke Dept Elect & Comp Engn Quebec City PQ Canada
In physical-layer network coding (PNC), the symbol detected at the relay node in two-way relay channels (TWRC) is the superposition of the symbols transmitted by the sinks. We refer to these symbols as pnc-symbols. In... 详细信息
