I don't know if I would call it overkill. It is just one of several methods you can use to achieve synchronization. Other options for synchronization include correlate and sync (probably needs modification), or possible the polyphase resync. Others on the list would have more expertise on these

Thanks guys for the information, I looked a little about the M&M recovery block but it seemed to me like and advance algorithm, overkill for what I'm trying to achieve. I'm I mistaken? If I'm using the M&M clock recovery block what is the quality of input signal I should aim to avoid translation

Depending on various factors the implementation may vary, but you could probably start with a chain that looks something like this: I/q source -> filter -> AGC -> AM demod (complex to mag) -> scaling for am depth -> m&m clock recovery -> slicer -> do something with the data Other, more advanced i

2014-04-09 Thread Robert McGwier
First 100k is insufficient sample rate from the E110. An FM station has 150 kHz total swing (+/- 75 kHz) so the frequency range of your E110 complex output is 100 kHz and is therefore insufficient for the entire modulation. You then feed the 100k sample per second signal into the FM block where
