Modular CSI Quantization for FDD Massive MIMO Communication
Jialing Liao, Roope Vehkalahti, Tefjol Pllaha +2
We consider high-dimensional MIMO transmissions in frequency division duplexing (FDD) systems. For precoding, the frequency selective channel has to be measured, quantized and fed…
Device-to-Device Data Storage with Regenerating Codes
Joonas Pääkkönen, Camilla Hollanti, Olav Tirkkonen
Caching data files directly on mobile user devices combined with device-to-device (D2D) communications has recently been suggested to improve the capacity of wireless net6works. We…
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.…
