[Discuss-gnuradio] Reg. AGC3 in gnuradio
Can someone give me detailed information about the new agc (agc3) in gnuradio?.Also is that agc a log mag. loop which is normally used in the modern receivers?If there is a block diagram of the new agc3 then it would also help. Thanks ahead. -- Thanks Regards Vamshi ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

http://gnuradio.squarespace.com/storage/tutorial/rondeau-costterra2.pdf Hi all, why does the output of PSK Mod block is imperfect, compared to theoritical QPSK constellation.( iam implementing qpsk with 4 sampl/sym and 4 constellation points).The experiment im doing is the same in link ( http://gnuradio.squarespace.com/storage/tutorial/rondeau-costterra2.pdf). -- Thanks Regards Vamshi Krishna. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] how to get started with python in gnuradio
Hi all It would be very helpful to me if some one tells me how to get started with python in gnu radio.I see an entire page dedicated to python programming but it does not say anything about getting started.Please don't say to use#!/usr/bin/env/python part in that page.Any link to how to get started with an example would be helpful. -- Thanks Regards Vamshi Krishna Dodla ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] tx rx using 2-usrp N210 and RFX2400 setup
I am new to the gnu radio community, and want to know how my set up works over the air. I am using GNU Radio and 2- usrp N210's with RFX2400. Can some one provide an example .grc files for a digital modulation (like qpsk) so as to verify over the air transmission.I need to know how UHD works and how USRP's connect from tx pc to rx pc. Any replies with examples would be helpful. -- Thanks Regards Krishna ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

[Discuss-gnuradio] Reg. Frequency response function in interpolator
Hi I need some information regarding frequency response function in the interpolator, does that use 1/f roll off or does it use the remez rolloff ? If it uses 1/f roll off i need some info on how it is done.Kindly provide me some documentation, as lack of the necessary info is hindering my project.

[Discuss-gnuradio] Need help
can some one send me a flow graph of QPSK transmitter and receiver, this flow graph should include a root raised cosine filter, qpsk generator, multipath channel, additive gaussian noise source, snr estimator and feed back, interpolator, carrier recovery using bandedge filters, timing recovery using poly phs clock sync, lms equalizer, coastas detector. I tried doing the same but having hard time executing the flow graph. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] (no subject)
I have some questions regarding the coastas loop implemented, does it also consider the snr estimate too? like a Maximum Likelihood loop(tanh* snr). Also can you suggest me any interpolator for timing recovery and also polyphase bandedge filters implementation. This would be really helpful to me.As there is very little material available online, also as you are experts in these fields your guidance will be very useful ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
