A Scalable VLSI Architecture for Soft-Input Soft-Output Depth-First Sphere Decoding
Ernst Martin Witte, Filippo Borlenghi, Gerd Ascheid +2
Multiple-input multiple-output (MIMO) wireless transmission imposes huge challenges on the design of efficient hardware architectures for iterative receivers. A major challenge is…
Efficient And Portable SDR Waveform Development: The Nucleus Concept
Venkatesh Ramakrishnan, Ernst M. Witte, Torsten Kempf +5
Future wireless communication systems should be flexible to support different waveforms (WFs) and be cognitive to sense the environment and tune themselves. This has lead to tremen…
Complexity-Efficient Enumeration Techniques for Soft-Input, Soft-Output Sphere Decoding
Konstantinos Nikitopoulos, Dan Zhang, I-Wei Lai +1
In this paper two complexity efficient soft sphere-decoder modifications are proposed for computing the max-log LLR values in iterative MIMO systems, which avoid the costly, typica…
