Hello Rita's pcf I'm trying to use the trellis encoder with the ofdm mod and the ofdm demod too. Could you please tell me why it can't be used just by connecting the trellis encoder's output with the ofdm mod's input. Did you find a way to do this? Please forgive me for my english -- View th

Hi DCardona, you should be able to do that -- could you explain what *doesn't work*? Your problem description is too vague to help you. By the way, your English is excellent; don't worry. but: who is Rita, and what's her pcf? Best regards, Marcus On 05/31/2015 04:39 PM, dcardona wrote: > Hello

Hi Marcus Thank you for your quick response. I think it works. I mean, i'm using an Error Rate block to compare the Trellis Enoder's output and the Viterbi Combos' output (I'm also doing this with the PCCC Encoder and the PCCC Decoder Combo blocks) and the results is 0 (like it should be). But i

The new GRC theme system using qss files looks pretty neat and seems very user configurable. Thanks. To use this, with my build-gnuradio installed setup, I had to create a new file under my home user folder at /home/me/.gnuradio/config.conf and I had to add the following to that file. [QTGUI] qss

Dear Iluta, in SDRA we don't have a specific talk on extraterrestrial radio applications, but the entire HAMRADIO event is on Space Applicatons. So it depends on which event you plan to attend. Generally you can say that the entire event is a lot of fun and allows people to bring their own stu

Try removing these lines from the DisplayPlot {} section: qproperty-line_style1: SolidLine; qproperty-line_style2: DashLine; qproperty-line_style3: DotLine; Since the lines are also in Frequency plot and Vector plot sections, that change should not affect them. It might mess up a Ti

Good evening, I will appreciate your help and guidance. since 3 weeks I'm trying to implement an application to derive the sky noise and attenuation from a beacon satellite signal. Using gnuardio and USRP2 (Ettus N210) I'm able to receive the and see the beacon signal at a defined frequency (FF

Hi Abdeslam, I assume you already have definite formulas that define the estimator for these two numbers. Unless you can directly "click together" that estimator in GRC, you will most likely have to implement it. In many cases, doing this in Python is rather easy (especially if you come from a pyt
