Log-likelihood ratio clipping in MIMO-BICM systems: Information geometric analysis and impact on system capacity
The clipping of log-likelihood ratios (LLRs) in soft demodulators for multiple-input multiple-output (MIMO) systems with bitinterleaved coded modulation (BICM) was recently observ...

Collapsible Pushdown Automata and Recursion Schemes
Collapsible pushdown automata (CPDA) are a new kind of higher-order pushdown automata in which every symbol in the stack has a link to a stack situated somewhere below it. In addi...
