For implementation some communication protocol like bluetooth, 4G,3G and wi-fi we need flow control mechanism.So we want to discuss can todays processors can handle these mechanisms. Soon i shared my search and result here.
Finally we worked on RTL-SDR and HackRF One and USRP in practical test and different moudlation like GFSK,DVB-T,ATSC,OFDM,DMR.With all of them we can see spectrum, it is not final purpose, we emphasize ,purpose is data in digital radio communication.So which SDR hardware can handle data extracting with different moudation and protocols like GSM or even LTE and so on.

Today we share recorded video DVB-T receiver here, we use two Hackrf One with Gnuradio, we had 1MB bandwidth and 461M center frequency.In higher bandwidth we had not any ofdm symbol and we had error restart aquisition for more info please see former our blog post this and that link. So really HackRF One in Higher 1MB bandwidth is not good and it can not haldle high carrier modulation.
We now disscuss about synchronization, this subject is one of most important challeneg in multi hardware digital communication.We have two general mechanism for sychronization, hardware based we use external clokc, other way .i.e. software based is same clock recovery.So here we discuss about hardware synchronization implentation,
