An Asymptotic Analysis of the MIMO BC under Linear Filtering
Raphael Hunger, Michael Joham
We investigate the MIMO broadcast channel in the high SNR regime when linear filtering is applied instead of dirty paper coding. Using a user-wise rate duality where the streams of…

On the Convexity of the MSE Region of Single-Antenna Users
Raphael Hunger, Michael Joham
We prove convexity of the sum-power constrained mean square error (MSE) region in case of two single-antenna users communicating with a multi-antenna base station. Due to the MSE d…

A General Rate Duality of the MIMO Multiple Access Channel and the MIMO Broadcast Channel
Raphael Hunger, Michael Joham
We present a general rate duality between the multiple access channel (MAC) and the broadcast channel (BC) which is applicable to systems with and without nonlinear interference ca…
