Abstract--The optimization of the pilot overhead in singleuser wireless fading channels is investigated, and the dependence of this overhead on various system parameters of interes...
— In this paper, we consider single user throughput optimization problem for continuous flat fading channels of multiple-input multiple-output (MIMO) system. It is known that ch...
In this paper we show that, in case of uncertainties during the estimation, overconfident posterior probabilities tend to mislead the performance of soft-decoders. Maximum likeliho...
—In this paper, we propose two robust precoder designs for multiple-input multiple-output (MIMO) broadcast channels with imperfect channel state information (CSI). First, we cons...
In this contribution iteratively detected spatial division multiplexing is investigated under the constraint of a fixed data throughput. Existing bit loading and transmit power a...
