Cognitive radios hold tremendous promise for increasing spectral efficiency in wireless
systems. This paper surveys the fundamental capacity limits and associated transmission …

We provide inner bound and outer bound for the total number of degrees of freedom of the K
user multiple-input multiple-output (MIMO) Gaussian interference channel with M antennas …

The throughput of existing MIMO LANs is limited by the number of antennas on the AP. This
paper shows how to overcome this limit. It presents interference alignment and cancellation …

In this paper, we develop the machinery of real interference alignment. This machinery is
extremely powerful in achieving the sum degrees of freedom (DoF) of single antenna …

The degree-of-freedom (DoF) regions are characterized for the multiple-input multiple-output
(MIMO) broadcast channel (BC), interference channels (ICs), including X and multihop ICs …

The degrees of freedom (DoF) region of the two-user multiple-input multiple-output (MIMO)
interference channel (IC) is studied under the assumptions of fast fading and delayed …

We study the effect of the absence of channel knowledge at the transmitters for multiple-
input-multiple-output (MIMO) networks. Specifically, we assume perfect channel state …

The author presents a unified treatment of this highly interdisciplinary topic to help define the
notion of cognitive radio. The book begins with addressing issues such as the fundamental …

A novel coding scheme applicable in networks with single antenna nodes is proposed. This
scheme converts a single antenna system to an equivalent Multiple Input Multiple Output …

Improper Gaussian signaling has the ability over proper (conventional) Gaussian signaling
to improve the achievable rate of systems that suffer from interference. In this paper, we …
