[Discuss-gnuradio] Analog and Digital Transmission in parallel
Hello everybody Im creating multi mudulation transmitter - project at my university. I have a conceptual problem. I have analog modulations: AM, SSB, FM - narrow and wide and digital modulations: qam, qpsk, gfsk and I want to have largest bandwith as possible :) to transmit all modulations simultanously. Scheme of my transmitter is: / AM \ wav source (16 KHz) - Matrix multiply- SSB - Matrix Multiply -> USRP Dev - FM N - - FM W - - QAM - - QPSK - \ gfsk - And now is my question :) I have now Sample Rate for whole project and Device - 2Mega Samples When I want to transmit all analog modulations with rate o 2 MS it is good But when I want to add one of digital modulation to analog modulation, I get Underrun after 3 minutes. But best is that when I run all digital modulation (no analog modulation) it behave properly. I have put sample sate probes on all modulations and after WAV file and here can be interesting thing: 1) when analog is transmitted only output Sample Rate of WAV Source is 16 KHz, but when digital is send Sample Rate is 2.5 Mega samples Is it proper to send analog and digital modulation in parallel ?? I I see this, there are two different sample rate here ?! All The Best Przemek ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] question about bandwith B210 - USB3
Hello I need to generate as wide bandwith as possible. Yes I know that this is waste of energy, but beside this simple example I want to put some other channels. On my USRP B210 I can afford now about 18 MS. I read on Ettus page that B200 can tx about 40 - 60 MS - depends on USB driver. So 15 MS is 3 times slower :) Im very beginer with filters at gnu radio so I suppose that default filters can be not so good optimized and propably I will need it to fix it manually.

[Discuss-gnuradio] FSK - implementation
I have a question about BFSK/M-FSK modulations in GnuRadio. If I have a symbol 1 or 0 and it has got 64 samples (2 periods of sin/cos) and I want to modulate it with 2 different frequencies for example: f1 = 175 KHz = 5,7 us f2 = 225 KHz = 4,4 us Problem is that 0 or 1 binary are same width - 64 samples but width for cos/sin periods are diferent and longer period will be cut for shorter symbol. Do I need to generate two diferent symbols width for 0 or 1 ? what with bigger M-FSK ? thank you in advice :) -- Posted via http://www.ruby-forum.com/. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

[Discuss-gnuradio] Passing GUI widgets into hier block with parameters
Hello I have a question. I have created many hier blocks, and I would like to pass into sam values from GUI but when state is changing, it doesnt correspond to value inside a hier block. this is my flowgraph: http://postimg.org/image/qgaf705q1/a9569ee5/ With GUI Chooser I would like to change SideBand of SSB Modulation. It is working when block responsible for switching side bands is outside of hier block. but it doesnt work when it is inside. This is my hier block, but with removed block responsible for swithcing, only Parameter left. http://postimg.org/image/4sbalehpl/ Thank You Przemek Lewandowski ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
Re: [Discuss-gnuradio] Passing GUI widgets into hier block with parameters
Hello everybody, Is this question has some not understandable phrases or should I correct something :) ? or is it stupid question or so simple. I still have a problem. Normally is it correct to pass GUI state inside a hierarchical block or is it not allowed ?? All the best.

[Discuss-gnuradio] qtgui freq_sink_c - change minimal height
Hello again I have a question about height of frequency sink. Im writing in python totally new GUI, without help of GnuRadio Companion, and I have problems with space. So my question is: How can I change height of freq_sink_c component from qtgui module ??? It take 1/3 of my screen :) thank you Przemek Lewandowski ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] tx <-> rx transmission
Hello friends, does anybody know where I can find some full example with one way transmission in one of this modulations: m-psk, m-fsk, m-qam ??? - But not Differential m-psk I would like to see full recovery path (carrier, symbol, equalization) in radio receiver. I know that there is example on gnuradio site but it doesnt involve real devices, and if I tried myself to reconnect with devices this example I had few blocker-problems :) I have B210 and RTL. PS. What is a proper path of signal receiving in digital modulation receiver: in my logic : device -> clock recovery -> symbol recovery (costas loop) -> equalization ->demodulator -> packet deckoder ?? Thank you for any advice. Przemek Lewandowski ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
