Thanks I will try a simple one and report back.

Leech Sent: Monday, May 13, 2013 4:46 PM To: discuss-gnuradio@gnu.org Subject: Re: [Discuss-gnuradio] A question on gnuradio capacity of handling real time data streaming and signal processing with USRP N210 + gnuradio on host linux computer Dear Group, I have a need to do real time or near real time tracking (most likely phase-lock loop) of multiple narrow-band carriers/tones in a 1MHz band of signal input using USRP N210 and gnuradio running on a reasonable linux host. Say the carriers/tones are embedded in the band from -500 kHz to +500 kHz. If I want to lock on to 20 carriers in that band using gnuradio PLLs, will this choke up the computer? If there is a problem, I also would like to think how to reduce data rates. But I don't know whether multiple LO's are an option. Thanks for reading, LD The best thing to do is to put together a simulation, and see if your computer is up to the task or not. Something that we don't have a really good handle on in Gnu Radio is some estimates for the computational complexity of individual blocks in a flow graph. If we did, one could do some simple arithmetic: add up all the complexities of all the blocks on your "fast path" (by this I mean blocks that must necessarily operate at the input sample rate) multiply that by the sample rate That gives you an idea of the numbers of MFLOPS/GFLOPS required to support your application. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
