Hello Rich, although Ed commented on the latency issue, regarding your performance issue my 2 pence: From my experience, using a time domain equalizer with
100 taps is a huge computational burden. Imagine: You are expecting significant echos (to be equalized) of 100*4/250kHz=1,6 ms. I do not know your application, but for wireless this is a whole lot. BTW: I am about to use exactly your computer USRP setup. Best regards

Im Auftrag von Richard Bell Hello all, My question is, looking at my receiver flowgraph, would you think this design should push the limits of a good laptop?
Would you believe I could be constrained to near the lowest sample rate limit with this design? Laptop Specs: HP Elitebook 8570w, Core i7, 16 GB RAM, Ubuntu 14.04 I would be interested in hearing what sample rates other peoples QPSK radios run at with a USRP N210 and similar computer. Thanks, |
