Journal ArticleDOI
Efficient algorithm for decoding layered space-time codes
TL;DR: A new efficient decoding algorithm based on QR decomposition is presented, which requires only a fraction of the computational effort compared with the standard decoding algorithm requiring the multiple calculation of the pseudo inverse of the channel matrix.
Proceedings ArticleDOI
MMSE extension of V-BLAST based on sorted QR decomposition
TL;DR: A novel, computationally efficient algorithm for detecting V-BLAST architectures with respect to the MMSE criterion is presented, which utilizes a sorted QR decomposition of the channel matrix and leads to a simple successive detection structure.
Proceedings ArticleDOI
Near-maximum-likelihood detection of MIMO systems using MMSE-based lattice reduction
TL;DR: This paper adopts lattice-reduction-aided schemes to the MMSE criterion and proposes an alternative method based on an extended system model, which in conjunction with simple successive interference cancellation nearly reaches the performance of maximum-likelihood detection.
Journal ArticleDOI
Cloud technologies for flexible 5G radio access networks
Peter Rost,Carlos J. Bernardos,Antonio De Domenico,Marco Di Girolamo,Massinissa Lalam,Andreas Maeder,Dario Sabella,Dirk Wubben +7 more
TL;DR: How cloud technologies and flexible functionality assignment in radio access networks enable network densification and centralized operation of the radio access network over heterogeneous backhaul networks is discussed.
Journal ArticleDOI
Benefits and Impact of Cloud Computing on 5G Signal Processing: Flexible centralization through cloud-RAN
Dirk Wubben,Peter Rost,Jens Bartelt,Massinissa Lalam,Valentin Savin,Matteo Gorgoglione,Armin Dekorsy,Gerhard Fettweis +7 more
TL;DR: The benefits that cloud computing offers for fifth-generation (5G) mobile networks are explored and the implications on the signal processing algorithms are investigated.
