Proceedings ArticleDOI
Closed loop transmission with precoding selection in LTE/LTE-Advanced system
Zijian Bai,Christoph Spiegel,Guido H. Bruck,Peter Jung,Michael Horvat,Jens Berkmann,Christian Drewes,Bertram Gunzelmann +7 more
TL;DR: The authors conclude that the minimum post mean squared error based criterion is the optimal candidate for precoding matrix selection at the receiver in LTE compliant systems.
Journal ArticleDOI
Implementation-friendly synchronisation algorithm for DVB-T2
Alexander Viesmann,Andreas Waadt,Christoph Spiegel,Christian Kocks,Admir Burnic,Peter Jung,Guido H. Bruck,Jung-Geun Kim,Jae-guyn Lim,Hang Woo Lee +9 more
TL;DR: A modified, yet implementation-friendly synchronisation algorithm has been developed and simulation results show a similar performance for synchronisation and frequency offset estimation, as well as the detection of the signalling information contained in the preamble P1 with a significant reduction of the implementation complexity.
Proceedings ArticleDOI
On the physical layer performance with rank indicator selection in LTE/LTE-Advanced system
Zijian Bai,Christoph Spiegel,Guido H. Bruck,Peter Jung,Michael Horvat,Jens Berkmann,Christian Drewes,Bertram Gunzelmann +7 more
TL;DR: This manuscript focuses on the RI selection study and implementation in LTE and LTE-Advanced systems and illustrates the downlink performance evaluation and comparison with different RI selection schemes.
Proceedings ArticleDOI
On MIMO with successive interference cancellation applied to UTRA LTE
Zijian Bai,Jens Berkmann,Christoph Spiegel,Tobias Scholand,Guido H. Bruck,Christian Drewes,Bertram Gunzelmann,Peter Jung +7 more
TL;DR: In this paper, the authors discuss the deployment of spatial multiplexing in the UTRA LTE downlink and show that the performance of successive interference cancellation (SIC) based data detection techniques for MIMO-OFDM is beneficial.
Proceedings ArticleDOI
MIMO Schemes in UTRA LTE, A Comparison
TL;DR: The authors will discuss the deployment of spatial multiplexing in the UTRA LTE downlink and will show that the performance of successive interference cancellation (SIC) based data detection techniques for MIMO-OFDM is beneficial.
