Degrees of Freedom of Generic Block-Fading MIMO Channels without A Priori Channel State Information
Günther Koliander, Erwin Riegler, Giuseppe Durisi +1
We studynthe high-SNR capacity of generic MIMO Rayleigh block-fading channels in the noncoherent setting where neither transmitter nor receiver has a priori channel state informati…
Generic Correlation Increases Noncoherent MIMO Capacity
Günther Koliander, Erwin Riegler, Giuseppe Durisi +1
We study the high-SNR capacity of MIMO Rayleigh block-fading channels in the noncoherent setting where neither transmitter nor receiver has a priori channel state information. We s…
Almost Lossless Analog Signal Separation
David Stotz, Erwin Riegler, Helmut Bölcskei
We propose an information-theoretic framework for analog signal separation. Specifically, we consider the problem of recovering two analog signals from a noiseless sum of linear me…
A Lower Bound on the Noncoherent Capacity Pre-log for the MIMO Channel with Temporally Correlated Fading
Günther Koliander, Erwin Riegler, Giuseppe Durisi +2
We derive a lower bound on the capacity pre-log of a temporally correlated Rayleigh block-fading multiple-input multiple-output (MIMO) channel with T transmit antennas and R receiv…
Fixed Points of Generalized Approximate Message Passing with Arbitrary Matrices
Sundeep Rangan, Philip Schniter, Erwin Riegler +2
The estimation of a random vector with independent components passed through a linear transform followed by a componentwise (possibly nonlinear) output map arises in a range of app…
