— It is known that the capacity of parallel (multi-carrier) Gaussian point-to-point, multiple access and broadcast channels can be achieved by separate encoding for each subchann...
New upper bounds on the sum capacity of the two-user Gaussian interference channel are derived. Using these bounds, it is shown that treating interference as noise achieves the sum...
We explore the capacity and generalized degrees of freedom of the 2-user Gaussian X channel, i.e. a generalization of the 2-user interference channel where there is an independent...
Abstract--A multiple access channel and a point-to-point channel sharing the same medium for communications are considered. We obtain an outer bound for the capacity region of this...
Abstract-- The capacity region of the two-user Gaussian Interference Channel (IC) is studied. Two classes of channels are considered: weak and mixed Gaussian IC. For the weak Gauss...
