Demo: Non-classic Interference Alignment for Downlink Cellular Networks

摘要: Our demo aims at proving the concept of a recent proposed interference management scheme that reduces inter-cell in downlink without complex coordination, known as non-classic alignment (IA) scheme. We assume case where one main Base Station (BS) needs to serve three users equipments (UE) while another BS is causing interference. The primary goal construct ; i.e. each UE estimates and interfered channel coefficients, calculates optimal free directions dropped by interfering feeds them back which turn applies scheduling select best directions. Once build, we are able measure total capacity channel. run CorteXlab controlled hardware facility located Lyon, France with remotely programmable radios multi-node processing capabilities, illustrate achievable gain for different realizations.
