Social norm based incentive mechanisms for peer-to-peer networks
In this paper, we build an analytical framework for the design and analysis of a new family of social norm based incentive mechanisms for peer-to-peer (P2P) networks. With this fr...

Optimized capacity bounds for the MIMO relay channel
This paper addresses the optimization of upper and lower bounds on the capacity of the multiple-input multiple-output (MIMO) relay channel. In particular, we show that evaluating ...

A mode preserving particle filter
A new particle filtering technique is proposed which addresses the problem of mode preservation in the approximation of multi-modal posteriors. The key is a resampling step which...
