A High-Speed QR Decomposition Processor for Carrier-Aggregated LTE-A Downlink Systems

This paper presents a high-speed QR decomposition (QRD) processor targeting the carrier-aggregated 4 × 4 Long Term Evolution-Advanced (LTE-A) receiver. The processor provides robustness in spatially correlated channels with reduced complexity by using modifications to the Householder transform, such as decomposing-target redefinition and matrix real-valued decomposition. In terms of hardware desig

The Impact of Elevation Angle on MIMO Capacity

Many channel models for MIMO systems have appeared in the literature. However, with the exception of a few recent results, they are largely focussed on two dimensional (2D) propagation, i.e., propagation in the horizontal plane, and the impact of elevation angle is not considered. The assumption of 2D propagation breaks down when in some propagation environments the elevation angle distribution is

Performance modelling and simulation of the Mobile Cloud Network

The Mobile Cloud Network is an emerging distributed cloud infrastructure paradigm that attempts to accommodate the evolution of application’s execution paradigms and how content is distributed. The Mobile Cloud Network employs a distributed cloud infrastructure with data centres of varying capacity, embedded in the core and access networks. Resources are thinned over the network and arguably decay
