Gaussian interference channel capacity to within one bit
- 5534–5562, 2008. EURASIP Journal on Advances in Signal Processing
"... Abstract—The capacity of the two-user Gaussian interference channel has been open for 30 years. The understanding on this problem has been limited. The best known achievable region is due to Han and Kobayashi but its characterization is very complicated. It is also not known how tight the existing o ..."

Interference alignment and the degrees of freedom for the K-user interference channel
- IEEE TRANSACTIONS ON INFORMATION THEORY
, 2008
"... For the fully connected K user wireless interference channel where the channel coefficients are time-varying and are drawn from a continuous distribution, the sum capacity is characterized as C(SNR) = K 2 log(SNR) +o(log(SNR)). Thus, the K user time-varying interference channel almost surely has K ..."

Degrees of freedom for MIMO interference channel
- IEEE Transactions on Information Theory
, 2007
"... Abstract — We show that the exact number of spatial degrees of freedom for a two user nondegenerate (full rank channel matrices) MIMO Gaussian interference channel with M1,M2 (respectively) antennas at transmitters 1, 2 and N1, N2 antennas at the corresponding receivers, and perfect channel knowl-ed ..."

Capacity bounds for the Gaussian interference channel
- IEEE TRANS. INFORM. THEORY
"... The capacity region of the two-user Gaussian Interference Channel (IC) is studied. Three classes of channels are considered: weak, one-sided, and mixed Gaussian ICs. For the weak Gaussian IC, a new outer bound on the capacity region is obtained that outperforms previously known outer bounds. The cha ..."

Strong Interference Channel With Delay
"... The paper investigates the effect of link delay on the capacity region of the interference channel with strong interference. It is shown that the capacity region of the strong interference channel with unit delay on one of the cross links (SICD) is at least as large as that without delay. This is es ..."

Interference Channels with Source Cooperation
, 2009
"... Interference is a fundamental feature of the wireless channel. Cooperation among the radios has been shown to manage interference in a multiple unicast wireless network in a near optimal scaling law sense [4]. In this paper, we study the two user Gaussian interference channel where the source nodes ..."
