[Discuss-gnuradio] VOLK for outer product of two vectors?

2012-10-21 Thread Alex Zhang
Hi, I looked at the VOLK to find if there are existing method to calculate the outer product of two vectors, but found nothing about it. If no, I have to write a SIMD based outer product method by myself. Thanks, -- Alex, *Dreams can come true – just believe.* __

[Discuss-gnuradio] Phase Difference

2012-10-21 Thread Shih Oliver
Hi lists, I'm using a e100 to send a sinusoid signal to only one N200 through a splitter. The two received signals by the same N200 still shows a phase difference, and it appears that the phase differs from different runs. What should I do to get rid of the phase difference? Many thanks i

[Discuss-gnuradio] Timed commands capabilities

2012-10-21 Thread Nowlan, Sean
Hi all, Has anyone pushed timed commands to their limits? I have a few questions: 1) How many commands fit in the queue? 2) How far in the future can you schedule a timed command? 3) Does the set_command_time() call (and subsequent command call) block? Should these take roughly as much time as t

Hi All, I'm running a block that I finished in GRextras in the USRP E110. I built the grextras as: build/sudo cmake ../ build/sudo make build/sudo make install It finishes without errors, but when I run my example in E110: /python top_block.py. It gives the following error: *File "top_block.p
