Hello,
I'm following your CC1310 I/Q sample example and working on CC1310 Launchpad. I set my symbol rate to be the following value:
According to the I/Q sample application note :
The IQ sample rate is fixed to 4 times oversampling and the IQ sample size is 12 bits. This means that each IQ pair will occupy 3 bytes in RAM.
1. Could you please tell me how could I calculte my I data sample rate and Q data sample rate based on my RF symbol rate setting?
2. When we are processing the I/Q samples, do we need to downsample 4 times or the I/Q sample output has already been averaged after your oversampling?
Thank you so much!
Is the symbol rate corresponding to the receiver ADC sampling rate? As there is no modulation, symbol rate should be data rate. If so, how could I back calculate ADC sample rate by using symbol rate? I/Q samples are all 12bits. Should I calculate by doing Symbol rate / 12 or Symbol rate / 24?
