Hi Ptolemy Hackers, I am using PTOLEMY version 0.6 on Solaris 2.6. I am trying to model a Direct Sequence Spread Spectrum tranceiver on SDF domain. I have decided to implement Code synchronization, timing recovery, phase recovery, data detection in digital domain. Typically for my system code length is 8191( 2^13-1), chipping rate- 8.192 mcps, data rate-16 kbps. I am facing some problems in modelling the system. Can anybody give me some pointers on how to model such a system efficiently on PTOLEMY? If anybody is interested, I can post specific problems associated with the modelling. Second query is whether there is any USER contributed library on PTOLEMY site for free access? Thanking in advance.
