4. 2. Design of programmable multi-standard baseband processors

   Author : Anders Nilsson; Dake Liu; Gerhard Fettweis; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; DSP; baseband processor; ASIP; Computer engineering; Datorteknik;

   Abstract : Efficient programmable baseband processors are important to enable true multi-standard radio platforms as convergence of mobile communication devices and systems requires multi-standard processing devices. The processors do not only need the capability to handle differences in a single standard, often there is a great need to cover several completely different modulation methods such as OFDM and CDMA with the same processing device.

5. 3. Dynamically Reconfigurable Architectures for Real-time Baseband Processing

   Author : Chenxin Zhang; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reconfigurable Computing; Coarse-Grained Architecture; Dynamic Reconfiguration; SIMD; VLIW; ASIP; Vector Processor; Baseband Processing; OFDM; MIMO; Channel Estimation; Symbol Detection.;

   Abstract : Motivated by challenges from today's fast-evolving wireless communication standards and soaring silicon design cost, it is important to design a flexible hardware platform that can be dynamically reconfigured to adapt to current operating scenarios, provide seamless handover between different communication networks, and extend the longevity of advanced systems. Moreover, increasingly sophisticated baseband processing algorithms pose stringent requirements of real-time processing for hardware implementations, especially for power-budget limited mobile terminals.

6. 4. 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.
