Im transmitting by cc1350 launchpad microprocessor digital RF Packets, transmitted modulation FSK. bit rate of transmitting is 50Kbouad, frequency of transmitting is 868MHZ . Im sampling the signal(RF PACKETS) that Im transmitting by a dongle SDR-RTL and it samples on frequency 2048000Hz , I want to decode the RF packets that Im transmitting, so I build demodulator and I see the data of my RF packet which it's: (I plot it in matlab plot)
So if you see here on the plot it shows data of my sampled RF packet, and in order to decode it to 0/1 (binary), I want to do LPF in order to smooth/smear much more my received Rf packet "to look like smoothly sinusoidal"
any help how can I do that?
