Proceedings ArticleDOI
Self-Organizing Coalitions for Conflict Evaluation and Resolution in Femtocells
Luis Guilherme Uzeda Garcia,Gustavo Wagner Oliveira Da Costa,Andrea F. Cattoni,Klaus I. Pedersen,Preben Mogensen +4 more
TL;DR: In this article, the authors presented a novel method inspired by graph and coalitional game theories to solve the conflicts among femtocells competing for a limited amount of resources in the network.
Proceedings ArticleDOI
On the benefits of early HARQ feedback with non-ideal prediction in 5G networks
Gilberto Berardinelli,Saeed R. Khosravirad,Klaus I. Pedersen,Frank Frederiksen,Preben Mogensen +4 more
TL;DR: The potential of using an early HARQ feedback in 5G networks considering the occurrence of wrong predictions is discussed and numerical analysis shows the potential of the early feedback of reducing the over-the-air latency up to 50%.
Proceedings ArticleDOI
On the capacity of a GSM frequency hopping network with intelligent underlay-overlay
TL;DR: Simulations have indicated that for slow moving mobiles a gain of approximately 35% is achieved by this new feature when compared with a frequency hopping network, and modifications are proposed to optimise the simulated algorithms, to improve the capacity in terms of carried traffic per cell even further.
Proceedings ArticleDOI
Performance analysis for UMTS downlink receiver with practical aspects
TL;DR: The analog interface to the digital receiver is analyzed and an architecture including AGC and ADC is suggested and it is analyzed that an ADC with 4-5 bit and sampling of 4 times the chip rate will give an acceptable performance.
Proceedings ArticleDOI
SVD-Based vs. Release 8 Codebooks for Single User MIMO LTE-A Uplink
TL;DR: The suitability of two options for the closed loop precoded MIMO transmission in LTE-A uplink are discussed, one of which exploits the Singular Value Decomposition (SVD) of the channel matrix, which could theoretically achieve the MIMo capacity.
