Link Adaptation in Linearly Precoded Closed-Loop MIMO-OFDM Systems with Linear Receivers
Abstract--Upcoming multi antenna systems such as 3GPPLTE employ code book based multi-mode precoding in order to adapt to a wide range of channel conditions. Link adaptation, which...

Novel Tap-Wise LMMSE Channel Estimation for MIMO W-CDMA
—In this paper, a tap-wise LMMSE channel estimator for MIMO W-CDMA is derived. Descrambling operations applied to delayed versions of the received signal whiten the input signal....

Asymptotic statistics of mutual information for doubly correlated MIMO channels
In this paper, we derive the asymptotic statistics of mutual information for multiple-input multiple-output (MIMO) Rayleigh-fading channels in the presence of spatial fading correl...

Adaptive codebook for beamforming in limited feedback MIMO systems
—We propose a new scheme for limited feedback in MIMO systems. We consider transmit beamforming and receiver maximal ratio combining as a base for our work, and propose a novel b...

Degrees of Freedom and Sum Rate Maximization for Two Mutually Interfering Broadcast Channels
— In this paper, we derive a precise expression of spatial degrees of freedom (DOF) for two mutually interfering broadcast channels (IFBC) as a function of arbitrary numbers of t...
