Performance Analysis of Massive MIMO Downlink System with Imperfect Channel State Information
We investigate the ergodic sum rate and required transmit power of a single-cell massive multiple-input multiple-output (MIMO) downlink system. The system considered in this paper is based on two linear beamforming schemes, that is, maximum ratio transmission (MRT) beamforming and zero-forcing (ZF) beamforming. What’s more, we use minimum mean square error (MMSE) channel estimation to get imper...
متن کاملPerformance Analysis of Multi-User Massive MIMO Downlink under Channel Non-Reciprocity and Imperfect CSI
This paper analyzes the performance of linearly precoded time division duplex based multi-user massive MIMO downlink system under joint impacts of channel non-reciprocity (NRC) and imperfect channel state information (CSI). We consider a practical NRC model which accounts for transceiver frequency-response mismatches at both user equipment (UE) and base station (BS) sides as well as mutual coup...
متن کاملPerformance Analysis of MIMO-OFDM under imperfect channel state information
The demand for high data rates in fourth generation wireless communication systems (4G) is to provide low complexity and high reliable system. Orthogonal Frequency Division Multiplexing (OFDM) technique with multiple inputs and multiple outputs (MIMO) system are used to support 4G requirements under unstable fading channels. We propose a combined decision directed channel estimation with an exp...
متن کاملOutput feedback model reference adaptive control for multi-input-multi-output plants with state delay
Two new output feedback adaptive control schemes based on Model Reference Adaptive Control (MRAC) and adaptive laws for updating the controller parameters are developed for a class of linear multi-input–multi-output (MIMO) systems with state delay. An effective controller structure established on a new error equation parametrization is proposed to achieve tracking with the error tending to zero...
متن کاملState Dependent Multi channel Queuing System with Ordered Entry
In the present study, we analyze the multi-channel service system with ordered entryfrom finite-source and finite-storage at each channel. The arrival and service rates are assumedto be state dependent. The steady state probabilities of the system are obtained by usingChapmann-Kolmogorov equations. Some other performance indices viz. utilization of servers,expected number of units in the system...
