ICASSP 2014 - 2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
ICASSP 2014 will be the world s largest and most comprehensive technical conference focused on the many facets of signal processing and its applications. The conference will feature world-class speakers, tutorials, exhibits, and oral/poster sessions on the most up-to-date topics in signal processing research.
The OCEANS conference covers four days. One day for tutorials and three for approx. 450 technical papers and 150-200 exhibits.
The purpose of these workshops is to bring together individuals from the IEEE and elsewhere with common interests in digital signal processing resarch and signal processing education. The combined workshop will include 5-6 plenary talks and approximately 150 contributed papers.

We provide an overview of the extensive results on the Shannon capacity of single-user and multiuser multiple-input multiple-output (MIMO) channels. Although enormous capacity gains have been predicted for such channels, these predictions are based on somewhat unrealistic assumptions about the underlying time-varying channel model and how well it can be tracked at the receiver, as well as at the transmitter. ...

We consider block-based transmissions over doubly-selective wireless channels. It is well-known that orthogonal frequency division multiplexing decomposes linear time-invariant channels into a set of parallel (non-interfering) channels via a Fourier basis. In contrast, for time-varying channels, inter- channel interference occurs and may have a dramatic impact on the performance. Following a mean square error criterion, we propose an approximate eigenmode ...

While feedback does not increase the capacity of memoryless channels, the capacity of time-varying channels with feedback can be increased by exploiting the structure in the channel variations. Feedback information from the receiver is usually available at the transmitter only after some time delay. The capacity increase due to feedback depends on the feedback delay relative to the channel decorrelation ...
Zhou, H.; Razavi, S.M.; Ratnarajah, T.; Sellathurai, M. Acoustics, Speech and Signal Processing (ICASSP), 2013 IEEE International Conference on , 2013
It has been conjectured by Høst-Madsen and Nosratinia that the K-user single- input single-output (SISO) complex Gaussian interference channels with constant channel coefficients have merely one degree of freedom (DoF) regardless of the number of users, i.e., K. Then, Cadambe and Jafar introduced the idea of interference alignment (IA) being able to achieve K/2 DoF in time- varying SISO interference ...
Sadeghi, P.; Vontobel, P.O.; Shams, R. Information Theory, IEEE Transactions on , 2009
We consider the problem of minimizing upper bounds and maximizing lower bounds on information rates of stationary and ergodic discrete-time channels with memory. The channels we consider can have a finite number of states, such as partial response channels, or they can have an infinite state space, such as time-varying fading channels. We optimize recently proposed information rate bounds for ...
