Subject: | [Discuss-gnuradio] duration of uhd_rx_cfile script |
Date: | Wed, 14 Dec 2011 09:21:44 +0100 |
Hello all,I just measured the time the execution of uhd_rx_cfile.py takes all together. I used N=20000, samp-rate=1M and the rest was left to the default values.
In theory the taking of the samples should take T=N/B=20ms but I had to discover that the whole process is taking about 2s.
Does anybody know what exactly is taking so long and if there is a way to speed it up? Since I am actually planning to somehow use this script (or parts of it) in the context of spectrum sensing/monitoring for dynamic access, 2 seconds is definitely taking to long.
Thanks in advance. Sebastian
