On the Outage Capacity of Orthogonal Space-time Block Codes Over Multi-cluster Scattering MIMO Channels
Lu Wei, Zhong Zheng, Jukka Corander +1
Multiple cluster scattering MIMO channel is a useful model for pico-cellular MIMO networks. In this paper, orthogonal space-time block coded transmission over such a channel is con…
Locally Best Invariant Test for Multiple Primary User Spectrum Sensing
Lu Wei, Prathapasinghe Dharmawansa, Olav Tirkkonen
We consider multi-antenna cooperative spectrum sensing in cognitive radio networks, when there may be multiple primary users. A noise-uncertainty-free detector that is optimal in t…
On the Exact Distribution of the Scaled Largest Eigenvalue
Lu Wei, Olav Tirkkonen, Prathapasinghe Dharmawansa +1
In this paper we study the distribution of the scaled largest eigenvalue of complexWishart matrices, which has diverse applications both in statistics and wireless communications.…
