2D Markovian SS codes flatten time-frequency distribution of signals in asynchronous Gabor division CDMA systems
We propose a Gabor division (GD)-CDMA system which permits time and frequency offsets. Negatively correlated time- and frequency-domain spreading codes have shown to reduce the va...

Interference Analysis in Time and Frequency Asynchronous Network MIMO OFDM Systems
—It is well known that symbol timing offsets larger than the cyclic prefix as well as carrier frequency offsets between transmitter and receiver stations destroy the orthogonali...

dPAM: a distributed prefetching protocol for scalable asynchronous multicast in P2P systems
— We leverage the buffering capabilities of end-systems to achieve scalable, asynchronous delivery of streams in a peer-to-peer environment. Unlike existing cache-and-relay schem...

How Resilient are Distributed f Fault/Intrusion-Tolerant Systems?
Fault-tolerant protocols, asynchronous and synchronous alike, make stationary fault assumptions: only a fraction f of the total n nodes may fail. Whilst a synchronous protocol is ...
