2. 1. Decoupling and Evaluation of Multiple Antenna Systems in Compact MIMO Terminals

   Author : Hui Li; Sailing He; Cyril Luxey; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple antennas; mutual coupling; compact antennas; frequency reconfigurable antennas; pattern reconfigurable antennas; meta-material antennas; mobile antennas; fractal antennas; collocated antennas; antenna measurement.;

   Abstract : Research on multiple antenna systems has been a hot topic in recent years due to the demands for higher transmission rate and more reliable link in rich scattering environment in wireless communications. Using multiple antennas at both the transmitter side and the receiver side increases the channel capacity without additional frequency spectrum and transmitted power. READ MORE

4. 2. Efficient Processing and Storage for Massive MIMO Digital Baseband

   Author : Yangxurui Liu; Integrerade elektroniksystem; []
   Keywords : digital signal processor; baseband processing; parallel memories; data compression; channel sparsity; Reconfigurable computing; QR decomposition; resource scheduling; massive MIMO; MIMO; DVFS;

   Abstract : Driven by the increasing demands on data rate from applications, the wireless communication standard has for decades been evolving approximately at a pace of one generation per ten years. Following this trend, the ambitious plan to replace the current cellular mobile network standard (4G) with the next generation standard (5G) is going through the standardization phase and is getting close to its actual deployment.
