[Discuss-gnuradio] a single source module to generate a random sequence with a pre-ample in the front

2018-05-25 Thread Linda20071
There is an example on ettus website that uses a single source module to generate a random sequence with a preamble in the front (on the same field in this module's properties dialogue box). I think this is an example to show preamble synchronization. I simply couldn't find the website with this ex

Hi everyone, here is a new blog post about my latest progress of my MIMO project for GSoC. I implemented a differential STBC scheme which exploits transmit diversity with 2 transmit antennas (basically a 'differential

By the way, a physical hint: what you get when a plane approaches or leaves from you is a phase of the wave that /changes linearly over time/, if you think about it. A linearly over time changing phase is a frequency. What you want to model is probably Doppler frequency shift in addition to a ti

Hi! So, I guess, full sample delay is far too coarse for your application, right? Best regards, Marcus On Fri, 2018-05-25 at 00:46 +, Yeo Jin Kuang Alvin (IA) wrote: > Hi, > > I need to simulate propagation delay, for example, having a plane fly past > and have to collect data for 5 secs w

Hello John, I'm looking at this right now and can confirm that the head of rfnoc-devel is compatible with the latest GNU Radio. Can you please try rerunning cmake on UHD with -DRFNOC_ENABLE=true? The error I saw when switching branches was that the header was not installed. That is a core RFNoC

Hello, I apologize for my terminology, it is causing some confusion. If you download the source from https://github.com/EttusResearch/uhd. You can compile this version and it should work fine with latest version of GNU Radio. But this version is missing additional modules that are available in br

Thank you for the response. The issue that we have is that the latest UHD RFNOC version is not compatible with latest version of GNU Radio. So I must either compile older version in with newer compiler, or downgrade to a version that is compatible with UHD RFNOC. Upgrading UHD to latest version w

Hi John, GNU Radio versioning is totally independent from UHD versioning, and that's what's defining the compatibility with the FPGA image. So, you need to install the UHD that fits your FPGA image (or use an FPGA image that fits your installed UHD). Best regards, Marcus On Thu, 2018-05-24 at 13
