Detection of Gaussian constellations in MIMO systems under imperfect CSI
Abstract—This paper considers the problem of Gaussian symbols detection in MIMO systems in the presence of channel estimation errors. Under this framework we develop a computatio...

Beamforming with Finite Rate Feedback for LOS MIMO Downlink Channels
— We consider a MIMO line of sight (LOS) broadcast channel where each user has perfect knowledge of its own channel and feeds back ‘quantized’ channel information to the tran...

On the Impact of Channel Estimation Errors on MAC Protocols for MIMO Ad Hoc Networks
In this paper, we evaluate the performance of a Medium Access Control (MAC) protocol for MIMO ad hoc networks under imperfect channel estimation. To this end, we also present an an...

Single-carrier systems with MMSE linear equalizers: Performance degradation due to channel and CFO estimation errors
We assess the impact of the channel and carrier frequency offset (CFO) estimation errors on the performance of singlecarrier systems with MMSE linear equalizers. Performance degra...

Multiuser MIMO Downlink Transmission Over Time-Varying Channels
—— The performance of multiuser MIMO downlink systems with block diagonalization (BD) relies on the channel state information (CSI) at the transmitter to a great extent. For ti...
