Background
T-CID 6 of exact definition of the use of the term “symbol” in IEEE
This contribution reports on action items (1) – (3) in the recommended remedy
Lots of the terminology of "symbol" are used in D2 draft. The exact definition for "symbol" in standard is required.
Add the exact definition of "symbol" in VLC to 3.1 or 3.2.
Work in progress … 1) identify in the document where the term "symbol" is used 2) identify if symbol is taking on multiple meanings (overloaded) 3) define for each meaning "what is a symbol" for that particular usage 4) modify the text accordingly Assigned to Joachim to comply usages
