On the Capacity of Partially Cognitive Radios
G. Chung, S. Sridharan, S. Vishwanath +1
This paper considers the problem of cognitive radios with partial-message information. Here, an interference channel setting is considered where one transmitter (the "cognitive" on…
A Layered Lattice Coding Scheme for a Class of Three User Gaussian Interference Channels
Sriram Sridharan, Amin Jafarian, Sriram Vishwanath +2
The paper studies a class of three user Gaussian interference channels. A new layered lattice coding scheme is introduced as a transmission strategy. The use of lattice codes allow…
Capacity of Symmetric K-User Gaussian Very Strong Interference Channels
Sriram Sridharan, Amin Jafarian, Sriram Vishwanath +1
This paper studies a symmetric K user Gaussian interference channel with K transmitters and K receivers. A "very strong" interference regime is derived for this channel setup. A "v…
On the Capacity of a Class of MIMO Cognitive Radios
Sriram Sridharan, Sriram Vishwanath
Cognitive radios have been studied recently as a means to utilize spectrum in a more efficient manner. This paper focuses on the fundamental limits of operation of a MIMO cognitive…
