How can I determine the bit rate or symbol rate?

Post by nicklang909 » Tue Mar 01, 2016 1:33 pm

Hi,

Very new to SDR and DSP, I'm trying to decode this signal from a temperature sensor (433 MHz using ASK).

I see the signal (attached) and have all the samples in a numpy array, but I'm not sure what to do now.

I believe I need to determine the baud or symbol rate so that I know how to interpret the up/down of the signal, but I'm not sure how to do that. How can I determine the baud or symbol or bit rate?

Thanks!
