— We provide achievability as well as converse results for the degrees of freedom region of a MIMO X channel, i.e., a system with two transmitters, two receivers, each equipped w...
—The degrees of freedom (DoF) of K-user MIMO interference networks with constant channel coefficients are not known in general. Determining the feasibility of a linear interfere...

In this paper, we provide a new achievable ergodic secrecy rate region for the multiple access wiretap channel in fading. Our achievable scheme is based on repeating each symbol at...
—We consider a scenario where multiple pairs of users exchange information within pair with the help of a dedicated multi-antenna relay. The co-channel interference among multipl...
