Robust Precoding Formulti-user Miso Systems with Limited-feedback Channels
InMulti User Multiple Input Single Output (MU-MISO) systems one centralized transmitter with multiple antennas serves several decentralized single-antenna receivers. Precoding is an attractive way to remove multiuser interferences because it reduces cost and power consumption in the user equipment. When implementing precoding, however, the base station should know the Channel State Information ...
متن کاملUtilization of Blind Source Separation Algorithms for MIMO Linear Precoding
In this paper we investigate the application of Blind Source Separation (BSS) algorithms for the decoding of linearly precoded MIMO communication systems and for the design of limited feedback channels that send the Channel Status Information (CSI) from the receiver to the transmitter. The advantage of using BSS is that the MIMO channel can be continuously tracked without the need of pilot symb...
متن کاملPerformance of MIMO systems in measured indoor channels with transmitter noise
This study analyzes the impact of transmitter noise on the performance of multiple-input multiple-output (MIMO) systems with linear and nonlinear receivers and precoders. We show that the performance of MIMO linear and decision-feedback receivers is not significantly influenced by the presence of transmitter noise, which does not hold true in the case of MIMO systems with precoding. Nevertheles...
متن کاملQoS Constrained Power Minimization in the MISO Broadcast Channel with Imperfect CSI
We consider the design of linear precoders and receivers in a Multiple-Input Single-Output (MISO) Broadcast Channel (BC). We aim at minimizing the transmit power while fullfiling a set of per-user Quality-of-Service (QoS) constraints expressed in terms of per-user average rate requirements. The Channel State Information (CSI) is assumed to be perfectly known at the receivers but only partially ...
متن کاملMMSE precoding for multiuser MISO downlink transmission with non-homogeneous user SNR conditions
This paper is concerned with linear precoding designs for multiuser downlink transmissions. We consider a multiple-input single-output (MISO) system with multiple single-antenna user equipment (UE) experiencing nonhomogeneous average signal-to-noise ratio (SNR) conditions. The first part of this work examines different precoding schemes with perfect channel state information (CSI) and average S...
