NT-Atom: building tools for performance studies

Code instrumentation is a powerful mechanism for understanding program behavior. Unfortunately, code instrumentation is extremely difficult, and therefore has been mostly relegated to building special purpose tools for use on standard industry benchmark ...

We consider coded modulation schemes for the block-fading channel. In the setting where a codeword spans a finite number N of fading degrees of freedom, we show that coded modulations of rate R bit per complex dimension, over a finite signal set ýýC of ...

Recently, the integration of cooperation with coding has proven to be a very useful technique to enhance relay system performance. Relay systems based on low-density parity-check (LDPC) codes have the potential to approach the theoretical information ...
