User Selection for Multiple-Antenna Broadcast Channel with Zero-Forcing Beamforming
Abstract—This paper investigates the zero-forcing (ZF) beamforming transmit strategy in the multiple-antenna multiuser downlink systems. We consider the case of mobile users equi...

Informed source separation of underdetermined instantaneous stereo mixtures using source index embedding
In this paper, we address the issue of underdetermined source separation of non-stationary audio sources from a stereo (i.e. 2-channel) linear instantaneous mixture. This problem ...

Many-to-Many Traffic Grooming in WDM Mesh Networks
In many-to-many communication, a session consists of group of users (we call them members) where each one of the members transmits its traffic to all other members in the group. Th...

Collision Helps - Algebraic Collision Recovery for Wireless Erasure Networks
Current medium access control mechanisms are based on collision avoidance and collided packets are discarded. The recent work on ZigZag decoding departs from this approach by recov...

Towards an Efficient Tile Matrix Inversion of Symmetric Positive Definite Matrices on Multicore Architectures
The algorithms in the current sequential numerical linear algebra libraries (e.g. LAPACK) do not parallelize well on multicore architectures. A new family of algorithms, the tile a...
