Rate-Based versus Distortion-Based Optimal Joint Source-Channel Coding
- We consider a joint source-channel coding system that protects an embedded wavelet bitstream against noise using a finite family of channel codes with error detection and error c...

Joint Optimal Channel Probing and Transmission in Collocated Wireless Networks
— We consider a collocated wireless network where all links contend for a given channel and each link can hear others’ transmissions. Due to channel fading, the link condition ...

Precoding for Outage Probability Minimization on Block Fading Channels
The outage probability limit is a fundamental and achievable lower bound on the word error rate of coded communication systems affected by fading. This limit is mainly determined ...

Symbolic performance analysis of elastic systems
Elastic systems, either synchronous or asynchronous, can be optimized for the average-case performance when they have units with early evaluation or variable latency. The performan...
