Yes I thik it gives the baseband data after passing through DAC/ADC . The thing which you are explaining is the processing which we can do locally. But the USRP gives the data after sampling. I do not want to make things complicated. I am pretty confused to buy it or not for this operation.

Well, is the usrp able to give you baseband data? I did some very very rough benchmarks for each of the 2 C66DSP's, several months ago showing Each C66DSP: Fs = 100kHz. 60, 152 tap FIR filters Close to 100% utilization for each C66 core. Assuming C66's are clocked at 750 MHz. There's also a

Thing is USRP can transmit data through USB 3.0 at max speed it can. But Can this board process it ?. It should because it has USB 3.0 port. I am not sure about the Bus speed of the board and other things On Tuesday, August 7, 2018 at 7:16:52 PM UTC+3, syed hashir wrote: > > Hello all, > > I

I am not sure about dma and buffers. I dont have good knowledge of it. I just want to use normal gnu radio block diagram on X15. Even on my high speed computer (not so much high but good atleast). If I increase the sampling rate more than 40MHz. Gnu radio shows overflow and underrun error.

So then data is coming from the IQ demodulator at 40 MHz on the USB 3.0 bus from the b210, and you 'd like to have it fill up a buffer via DMA, and then generate an interrupt for one or both C66 DSP's to demodulate, filter, downsample, filter some more, perform error correction coding, until
