Dynamic scheduling and synchronization synthesis of concurrent digital systems under system-level constraints
We present in this paper a novel control synthesis technique for system-level specifications that are better described as a set of concurrent synchronous descriptions, their synch...

On the implementation of MIMO-OFDM schemes using perturbation of the QR decomposition: Application to 3GPP LTE-a systems
Consider a flat-fading Multiple-Input Multiple-Output (MIMO) system. The near-optimum detection problematic has been shown to be efficiently solved through QR Decomposition (QRD...

Computationally efficient equalization of room impulse responses robust to system estimation errors
Equalization techniques for room impulse responses (RIRs) are important in acoustic signal processing applications such as speech dereverberation. In practice, only approximate es...
