On the Compound MIMO Broadcast Channel
نویسندگان
چکیده
We consider the Gaussian multi-antenna compound broadcast channel where one transmitter transmits several messages, each intended for a different user whose channel realization is arbitrarily chosen from a finite set. Our investigation focuses on the behavior of this channel at high SNRs and we obtain the multiplexing gain of the sum capacity for a number of cases, and point out some implications of the total achievable multiplexing gain region.

Semi-Blind Channel Estimation based on subspace modeling for Multi-user Massive MIMO system
Channel estimation is an essential task to fully exploit the advantages of the massive MIMO systems. In this paper, we propose a semi-blind downlink channel estimation method for massive MIMO system. We suggest a new modeling for the channel matrix subspace. Based on the low-rankness property, we have prposed an algorithm to estimate the channel matrix subspace. In the next step, using o...
متن کاملOn the capacity of multiple input multiple output broadcast channels
Abstract— We consider a multi-user multiple input multiple output (MIMO) Gaussian broadcast channel (BC), where the transmitter and receivers have multiple antennas. Since the MIMO broadcast channel is in general a non-degraded broadcast channel, its capacity region remains an unsolved problem. In this paper, we establish a duality between what is termed the “dirty paper” achievable region (the...

In this paper, the spatial MIMO channel modeling (SCM) is introduced and the required parameters for this modeling are studied. Then, the MIMO channel gains and capacity are analyzed. The transmitter and receiver antenna patterns are also analyzed. Next, we are focused on the effects of the transmitter and receiver antenna arrays separations, the arrays length, and the angles spread on the ante...
متن کاملMultiuser MIMO degrees of freedom with no CSIT
We provide the characterization of the degrees of freedom (DOF) region for a 2-user fading MIMO broadcast channel when perfect channel knowledge is available to the receivers and no channel knowledge is available to the transmitters. The results are applied to find the DOF region for some special cases of a 2-user MIMO interference channel. We also extend the outerbound of the DOF region to fin...
