Re: [Discuss-gnuradio] How to implement 64QAM?

Hi, I haven't looked at any of the QAM-related code in the GNU Radio baseline, but it should be possible to design a generic MQAM demodulator. In fact, you should be able to build a generic MQAM demodulator for a given constellation set. This, I've done before in Matlab. You start with an A

[Discuss-gnuradio] Specs on OFDM demodulator for USRP 1,2

Hi, Does anyone have any specs on OFDM demodulator usage for the USRP 1 or 2 as in what kind of rates have you been able to process with it in real time? Thanks in advance, Isaac -- View this message in context: http://old.nabble.com/Specs-on-OFDM-demodulator-for-USRP-1%2C2-tp27343224p2734322

Re: [Discuss-gnuradio] Automatic Modulation Recognition

Eric, Im thinking I would just use a squaring, 4th power, 8th power, techniques and look for spectral peaks. What do you think? Isaac -- View this message in context: http://old.nabble.com/Automatic-Modulation-Recognition-tp26835383p26843607.html Sent from the GnuRadio mailing list archive a

Re: [Discuss-gnuradio] ENERGY DETECTOR

I implemented an energy detector on the GNU Radio by using a GPU at my old job. We used an FFT based method which is not uncommon. What you do is FFT the data and then compute the PSD. Do this in overlapping blocks (e.g. 12.5%, 50%, etc). You could optionally use a window too. Then, with the
