Article Information

1.	Cooperative diversity in wireless networks: Efficient protocols and outage behavior Laneman, J.N.; Tse, D.N.C.; Wornell, G.W. Information Theory, IEEE Transactions on Volume 50, Issue 12, Date: Dec. 2004, Pages: 3062- 3080 Digital Object Identifier 10.1109/TIT.2004.838089 Summary: We develop and analyze low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks. The underlying techniques exploit space diversity available through cooperating terminals' relaying signal...

2.	Compressed sensing Donoho, D.L. Information Theory, IEEE Transactions on Volume 52, Issue 4, Date: April 2006, Pages: 1289-1306 Digital Object Identifier 10.1109/TIT.2006.871582 Summary: Suppose x is an unknown vector in Ropf^m (a digital image or signal); we plan to measure n general linear functionals of x and then reconstruct. If x is known to be compressible by transform coding with a known transform, and we reconstruct ...

3.	Space-time codes for high data rate wireless communication:performance criterion and code construction Tarokh, V.; Seshadri, N.; Calderbank, A.R. Information Theory, IEEE Transactions on Volume 44, Issue 2, Date: Mar 1998, Pages: 744-765 Digital Object Identifier 10.1109/18.661517 Summary: We consider the design of channel codes for improving the data rate and/or the reliability of communications over fading channels using multiple transmit antennas. Data is encoded by a channel code and the encoded data is split into n streams that are...

4.	Cognitive Radio: An Information-Theoretic Perspective Jovicic, A.; Viswanath, P. Information Theory, IEEE Transactions on Volume 55, Issue 9, Date: Sept. 2009, Pages: 3945-3958 Digital Object Identifier 10.1109/TIT.2009.2025539 Summary: In this paper, we consider a communication scenario in which the primary and the cognitive radios wish to communicate to different receivers, subject to mutual interference. In the model that we use, the cognitive radio has noncausal knowledge of the ...

5.	Capacity theorems for the relay channel Cover, T.; Gamal, A.E. Information Theory, IEEE Transactions on Volume 25, Issue 5, Date: Sep 1979, Pages: 572- 584 Digital Object Identifier Summary: A relay channel consists of an inputx_{l}, a relay outputy_{1}, a channel outputy, and a relay senderx_{2}(whose transmission is allowed to depend on the past symbolsy_{1}. The dependence of the ...

6.	The capacity of wireless networks Gupta, P.; Kumar, P.R. Information Theory, IEEE Transactions on Volume 46, Issue 2, Date: Mar 2000, Pages: 388-404 Digital Object Identifier 10.1109/18.825799 Summary: When n identical randomly located nodes, each capable of transmitting at W bits per second and using a fixed range, form a wireless network, the throughput λ(n) obtainable by each node for a randomly chosen destination is Θ(W/√(nlog...

7.	Network information flow Ahlswede, R.; Ning Cai; Li, S.-Y.R.; Yeung, R.W. Information Theory, IEEE Transactions on Volume 46, Issue 4, Date: Jul 2000, Pages: 1204-1216 Digital Object Identifier 10.1109/18.850663 Summary: We introduce a new class of problems called network information flow which is inspired by computer network applications. Consider a point-to-point communication network on which a number of information sources are to be multicast to certain sets of de...

8.	Writing on dirty paper (Corresp.) Costa, M. Information Theory, IEEE Transactions on Volume 29, Issue 3, Date: May 1983, Pages: 439- 441 Digital Object Identifier Summary: A channel with outputY = X + S + Zis examined, The stateS sim N(0, QI)and the noiseZ sim N(0, NI)are multivariate Gaussian random variables (Iis the identity matrix.). The inputX in R^{n}satisfie...

9.	Channel coding with multilevel/phase signals Ungerboeck, G. Information Theory, IEEE Transactions on Volume 28, Issue 1, Date: Jan 1982, Pages: 55- 67 Digital Object Identifier Summary: A coding technique is described which improves error performance of synchronous data links without sacrificing data rate or requiring more bandwidth. This is achieved by channel coding with expanded sets of multilevel/phase signals in a manner which ...

10.	The Generalized Area Theorem and Some of its Consequences Measson, C.; Montanari, A.; Richardson, T.J.; Urbanke, R. Information Theory, IEEE Transactions on Volume 55, Issue 11, Date: Nov. 2009, Pages: 4793-4821 Digital Object Identifier 10.1109/TIT.2009.2030457 Summary: There is a fundamental relationship between belief propagation (BP) and maximum a posteriori decoding. The case of transmission over the binary erasure channel was investigated in detail in a companion paper (C. MEacuteasson, A. Montanari, and ...
