[Discuss-gnuradio] radio control transmitter signal

2005-05-04 Thread cswiger
Gang - Here's a little bit on receiving a model aircraft R/C transmitter signal. Get a great demod PPM output - the challenge would be to write a signal processing block to output each channel position. Switching to PCM might be easier to work with tho. http://webpages.charter.net/cswiger/rc_nbfm.

[Discuss-gnuradio] Questions on DDC's

Guys, I remember someone gave me an answer to a similar question in the past regarding the Digital upconverter in the TX path that is implemented inside the ADC chip. I have a similar question for the DDC in the RX path which is implemented in the FPGA: On the receiver path, the DDCs perform com

[Discuss-gnuradio] Question on DDC/USB interface

Guys, How are the 4 complex streams out of the 4 DDCs multiplexed into the USB port? If the 4 ADCs sample at 64MSps, and each of the DDC's is downsampling by N, then there are 4 complex streams of 64/N MSps waiting to be transfered through the USB port. How do we control (if we can control) which

I think the issue of programming MAC layer interaction comes down to one of timing. I am still investigating gnuradio-to-USRP timings, but I am looking at simple integer writes to the daughterboard, driven from a python program loop, and seeing 1 to 5 per millisecond on the logic analyzer. Now, m

well, at least ten-tec is far more hobbyist-friendly compared to makers of comparably spec'd wide-coverage receivers...which are priced in the 5-figure range and are otherwise very difficult to obtain: http://www.drs.com/products/index.cfm?gID=17&productID=625 http://www.drs.com/products/index.cf
