On the outage and diversity-multiplexing tradeoff of broadcast channels with 1-bit feedback
In this paper, a single antenna downlink channel with K users is analyzed in the presence of Rayleigh flat fading. A limited channel state information (CSI) feedback scheme is co...

PHY-layer Fairness in Amplify and Forward Cooperative Diversity Systems
We deal with the concept of physical-layer fairness in amplify and forward cooperative diversity systems, which reflects the need for equally allocating the consumed power among th...

An efficient cut enumeration for depth-optimum technology mapping for LUT-based FPGAs
Recent technology mappers for LUT based FPGAs employ cut enumeration. Although many cuts are often needed to nd good network, enumerating all cuts with large size consumes run-tim...

A symbolic algorithm for low-power sequential synthesis
We present an algorithm that restructures the state transition graph STG of a sequential circuit so as to reduce power dissipation. The STG is modi ed without changing the behav...

Fault-tolerant compression filters by time-propagated measurement fusion
For fault-tolerant real-time filtering, an efficient two-filter architecture is proposed. In the two-filter architecture, a host filter is operated permanently. A compression filt...
