RE: [Discuss-gnuradio] Transmitting binary 1's and 0's using different modulation schemes
Hello everyone, Happy New Year! Does anyone have a solution to this post yet? Your help will be greatly appreciated. Thanks!

Also, is there a receiver that can take the transmitted signal, reduce it to baseband and then collect it's analog values using "gr.vector_sink_c()"?

I'm also running F10 with boost-1.37.
The instructions have you include /opt/boost{whatever}/lib in
LD_LIBRARY_PATH, but instead, I simply
do a "ldconfig /opt/boost{whatever}/lib", and then I don't have to
remember to stuff LD_LIBRARY_PATH
all the time.
I'm running on a quad-core Q6600 system, which I have overclocked to
about 2.95Ghz, from 2.4Ghz. It's just
barely able to keep up with two (complex, 8-bit) channels at 6.4Msps
for my radio astronomy stuff. I can't get
it to overclock any higher, until I get a cooler (currently using the
stock fan).
If I had the money, I'd upgrade to a 2U server with twin or quad-socket
Xeon 5472, but I can't quite justify that
expense after getting laid off a couple of months ago :-( :-(

You should also see a declaration "int usleep(...", which should prevent the error shown above. It sounds like configure thinks that it has found usleep, but when you go to compile it isn't found.

They ship kernel images compressed, and without symbols, and the older information on this (ca FC6) doesn't appear to work anymore--there's no "core-debuginfo" and "kernel-debuginfo" packages to install. So, to a first approximation, oprofile is next-to-useless for me.

Don,
Thanks for the input. The result of "fgrep -i sleep config.h" is:
fgrep -i sleep config.h
/* Define to 1 if you have the `nanosleep' function. */
/* #undef HAVE_NANOSLEEP */
/* Define to 1 if you have the `sleep' function. */
/* #undef HAVE_SLEEP */
/* Define to 1 if you have win32 Sleep */
#define HAVE_SSLEEP 1
/* Define to 1 if you have the `usleep' function. */
#define HAVE_USLEEP 1
#ifndef HAVE_USLEEP
int usleep(unsigned long usec); /* SUSv2 */
#ifndef HAVE_NANOSLEEP
static inline int nanosleep(const struct timespec *req, struct timespec *rem) {
return usleep(req->tv_sec*100+req->tv_nsec/1000); }
#if defined(HAVE_SSLEEP) && !defined(HAVE_SLEEP)
/* TODO: what about SleepEx? */
static inline unsigned int sleep (unsigned int nb_sec) { Sleep(nb_sec*1000);
return 0; }
1) I only installed MinGW yesterday and used MinGW-5.1.4.exe.
2) Using w32api3.11

Re: [Discuss-gnuradio] problem with carrier sense in USRP
hi, i also try to search for send_pkt() function..could any one tell me where to find this function in GNU radio package? i think it is on C++ code isn't it?but when i search in the CLASS list on http://gnuradio.org/trac/browser/gnuradio/trunk i couldn't find any..or maybe i miss it? please help me.. thank you. adib sairi Hi, I am testing the carrier sense mechanism on USRP based on code from benchmark_tx.py and tunnel.py. My scenario is to receive packets from two distinctive nodes simultaneously at the third node. I am prefixing the payload with sender node name to identify the sender. When I am trying to send the packets from two nodes simultaneously, the packets are still colliding, though I have incorporated carrier sense mechanism in to my code. Please help me in this respect and if possible suggest me a solution. I think, packets are being sent by the lower level C++ processing blocks and send_pkt() just enqueues the packets. So rather than holding sending of packet, this code is just holding the packet from getting enqueued in message queue. Which is not really the holding of packet till carrier is free. Once packets are in message queue, they are transmitted irrespective of carrier availability. So there is still possibility of packet collision. Am I correct in my understanding of this real-time scenario? -- View this message in context: http://www.nabble.com/problem-with-carrier-sense-in-USRP-tp20492283p21247975.html Sent from the GnuRadio mailing list archive at Nabble.com. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
