چکیده

For the two-user multiple-input multiple-output (MIMO) broadcast channel with delayed state information at transmitter (CSIT) and arbitrary antenna configurations, all degrees-of-freedom (DoF) regions are obtained. However, for three-user MIMO CSIT DoF region of order-2 messages is still unclear only a partial achievable order-1 obtained, where desired by two receivers one receiver, respectively. In this paper, we first design transmission schemes messages. Next, propose to analyze scheme transformation approach. particular, transform decoding condition w.r.t. phase duration into DoF, through tuple expression connecting DoF. As result, characterized an completely expressed. Besides, messages, derive sufficient condition, under which proposed region.

The Degrees of Freedom Regions of Two-User and Certain Three-User MIMO Broadcast Channels with Delayed CSIT

The degrees of freedom (DoF) region of the fast-fading MIMO (multiple-input multiple-output) Gaussian broadcast channel (BC) is studied when there is delayed channel state information at the transmitter (CSIT). In this setting, the channel matrices are assumed to vary independently across time and the transmitter is assumed to know the channel matrices with some arbitrary finite delay. An outer...

A Novel Proof for the DoF Region of the MIMO Broadcast Channel with No CSIT

In this paper, a new proof for the degrees of freedom (DoF) region of the K-user multiple-input multipleoutput (MIMO) broadcast channel (BC) with no channel state information at the transmitter (CSIT) and perfect channel state information at the receivers (CSIR) is provided. Based on this proof, the capacity region of a certain class of MIMO BC with channel distribution information at the trans...

DoF Analysis of the K-user MISO Broadcast Channel with Alternating CSIT

We consider a K-user multiple-input single-output (MISO) broadcast channel (BC) where the channel state information (CSI) of user i(i = 1, 2, . . . ,K) may be either perfect (P), delayed (D) or not known (N) at the transmitter with probabilities λP , λ i D and λ i N , respectively. In this channel, according to the three possible CSIT for each user, joint CSIT of the K users could have at most ...

On the DoF Region of the K-user MISO Broadcast Channel with Hybrid CSIT

An outer bound for the degrees of freedom (DoF) region of the K-user multiple-input single-output (MISO) broadcast channel (BC) is developed under the hybrid channel state information at transmitter (CSIT) model, in which the transmitter has instantaneous CSIT of channels to a subset of the receivers and delayed CSIT of channels to the rest of the receivers. For the 3-user MISO BC, when the tra...

Precoding Methods for MISO Broadcast Channel with Delayed CSIT

Recent information theoretic results suggest that precoding on the multi-user downlink MIMO channel with delayed channel state information at the transmitter (CSIT) could lead to data rates much beyond the ones obtained without any CSIT, even in extreme situations when the delayed channel feedback is made totally obsolete by a feedback delay exceeding the channel coherence time. This surprising...
