I need some help with a simple thing. I am trying to simulate carrier frequency offset model for Bluetooth Low Energy standard in GNURadio (I am bit new to this). For this purpose, there is a CFO model already available in it details of which are available here https://wiki.gnuradio.org/index.php/CFO_Model . I need to correctly parameterize the model with some values according to some of the knowns about the standard
Channel Bandwidth 2 MHz Frequency (f) 2.4 GHz Maximum crystal Oscilator inaccuracy (ppm) 20.8 ppm dictated by standard Maximum CFO bound (f*ppm/10^6) 49920 Hz over a packet Sample rate ( R ) 4 MHz 2*BW. I assume Sample duration (1/R) 0.00000025 s CFO standard deviation (Hz per sample) ? Can you please check if parameter values are correct. How can I determine the CFO standard deviation (Hz per sample) as described in the above link in this case? Regards, Yuxuan
