Parallel multiple-input multiple-output (MIMO) broadcast channels are separable from an information theoretic point of view, i.e., the whole capacity region can be achieved with strategies that perform independent encoding and decoding on each carrier subject to a power allocation across carriers. However, recent research has revealed that such a separate transmission can become suboptimal if t...

We consider a set of parallel, two-user Gaussian broadcast channels, where the transmitter wishes to send independent information to each of the receivers and common information to both receivers. The capacity region of this channel has been implicitly characterized in the past, but we provide an explicit characterization of the power and rate allocation schemes that achieve the boundary of the...

With the increasing number of Internet Things (IoT), Industry 4.0 (I4.0), and mobile devices, it can be expected that base stations will have to serve more clients with a limited antennas. For their broadcast channels, nonorthogonal multiple access (NOMA) blind interference alignment (BIA) are two efficient commonly adopted transmission schemes. This paper conducts comparison study on these tec...
