On Runlength Limited Codes for BICM Systems
Stephan Zeitz, Florian Roth, Meik Dörpinghaus, Gerhard Fettweis
We study the use of runlength-limited (RLL) block codes in bit-interleaved coded modulation (BICM) systems. In this setting, the RLL code acts as the symbol mapper, whose assignment between input bits and RLL symbols is critical for performance. In this work, we aim at optimizing…
