    Sammanfattning : The past decades have seen a rapid growth of mobile data traffic,both in terms of connected devices and data rate. To satisfy the evergrowing data traffic demand in wireless communication systems, thecurrent cellular systems have to be redesigned to increase both spectralefficiency and energy efficiency. LÄS MER

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

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

    Sammanfattning : 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.
