On Non-Stationary Urban Macrocell Channels in a Cooperative Downlink Beamforming Scenario
—A common simplification in the treatment of random linear channels is the assumption of stationarity of the channel in time. The wireless channel is, however, known to be inher...

A multi-threshold scheme for feedback load reduction in multiuser MIMO broadcast channel
In a multiuser system, independent time-varying channels among different users can be exploited to provide multiuser diversity (MUD) gain and increase the system throughput. For th...

On the Eigenvalue Distribution of Ricean MIMO Channels by Character Expansion of Groups
Abstract— Joint eigenvalue distribution of the noncentral complex Wishart matrix, i.e. HH∗ where H is the nonzero-mean complex Gaussian random channel matrix of a multiple-inpu...

Design of a Channel Characteristics-Aware Routing Protocol
Abstract—Radio channel quality of real-world wireless networks tends to exhibit both short-term and long-term temporal variations that are in general difficult to model. To maxi...

Outage Behavior of Quasi-Static Fading Channels with Partial Power Control and Noisy Feedback
Abstract— We investigate the outage behavior of multipleantenna slowly fading channels with resolution constrained feedback and partial power control. A fixed-rate communication...
