Transmit Precoding for the Multiple Antenna Broadcast Channel
— In this paper we compare the following two methods of transmit precoding for the multiple antenna broadcast channel: vector perturbation applied to channel inversion (also term...

Latency Constrained Aggregation in Sensor Networks
A sensor network consists of sensing devices which may exchange data through wireless communication. A particular feature of sensor networks is that they are highly energy constrai...

Robust transmit processing for frequency-selective fading channels with imperfect channel feedback
Reliable channel state information at the transmitter (CSIT) can improve the throughput of wireless networks significantly. In a realistic scenario, there is a mismatch between th...

Better extractors for better codes?
We present an explicit construction of codes that can be list decoded from a fraction (1 - ) of errors in sub-exponential time and which have rate / logO(1) (1/). This comes close...
