On the Secure Degrees of Freedom of Wireless X Networks
Tiangao Gou, Syed A. Jafar
Previous work showed that the X network with M transmitters, N receivers has MN/(M+N-1) degrees of freedom. In this work we study the degrees of freedom of the X network with secre…
Degrees of Freedom of the User MIMO Interference Channel
Tiangao Gou, Syed A. Jafar
We provide innerbound and outerbound for the total number of degrees of freedom of the user multiple input multiple output (MIMO) Gaussian interference channel with antenna…
Complexity of Decoding Positive-Rate Reed-Solomon Codes
Qi Cheng, Daqing Wan
The complexity of maximal likelihood decoding of the Reed-Solomon codes is a well known open problem. The only known result in this direction states that it is at leas…
A noisy system with a flattened Hamiltonian and multiple time scales
Natella V. O'Bryant
We consider a two-dimensional weakly dissipative dynamical system with time-periodic drift and diffusion coefficients. The average of the drift is governed by a degenerate Hamilton…
