Input Papers:
o Minutes of Fall 2004 Meeting for review of Action Items, etc.
o TC Channel Coding Green Book (Draft 2).
--------------Tuesday April 12 pm SLS-LEC BOF [Long Erasure Codes (aka Tornado Codes) BOF]
- Definition application scenarios for LEC taken from existing and planned/future missions
- Report statistical analysis on erasures derived from existing channels and define Channel
Reference Characteristics
