2. Unified SFD Proposal
(Doc and Doc )

3. Unified SFD values SFD Value for FEC SFD value for Non-FEC
Doc# proposed 3 SFDs (Plan A, B, and C) and Doc# proposed one SFD Plan D
As a result of discussion by proposers, Plan B is the mandatory SFD and Plan D is optional SFD.
The word “mandatory SFD” means that all g compliant devices need to implement the SFD .

4. Way Forward for SFD for MR-FSK
Define a PIB attribute with 0 indicating that the SFD’s are defined according to Plan B and with 1 indicating that the SFD’s are defined according to Plan D. It is mandatory that a device be capable of supporting Plan B SFD’s when the PIB attribute has value 0.

0 indicates that the SFD value for FEC is “ ” and the SFD value for non-FEC is “ ”; 1 indicates that the SFD value for FEC is “ ” and the SFD value for non-FEC is “ ”. The SFD is transmitted starting from the leftmost bit. It is mandatory that devices be capable of supporting the SFD’s associated with value 0 when value 0 is set.
