hello mahesh,
for this kind of question, you should download these documents:
http://www.3gpp.org/ftp/Specs/html-info/44-series.htm
44.006 and 44.018 specify the precise bit ordering
http://www.3gpp.org/ftp/Specs/html-info/45-series.htm
45.002, chapter 3.3.2.2.1 Synchronization channel (SCH) description
45.003 the channel coding of the SCH
45.010 defines how the TDMA frame number can be calculated from T1, T2, and T3′
i’m sorry, i don’t know the details for those channels because it’s totally useless for optimization 🙂
have fun 🙂
