— In this paper, we provide a lower and upper bound for the number of degrees of freedom (DOF) of B multipleinput single-output (MISO) broadcast channels (BC) where each base sta...
— In this paper, we derive a precise expression of spatial degrees of freedom (DOF) for two mutually interfering broadcast channels (IFBC) as a function of arbitrary numbers of t...
Interference alignment is a transmission technique for exploiting all available degrees of freedom in the symmetric frequency- or time-selective interference channel with an arbit...
—A contemporary perspective on the tradeoff between transmit antenna diversity and spatial multiplexing is provided. It is argued that, in the context of modern cellular systems ...
This paper considers the multi-input multi-output (MIMO) relay channel where multiple antennas are employed by each terminal. Compared to single-input singleoutput (SISO) relay ch...
