Re: [Discuss-gnuradio] Question about OFDM Transmitter/Receiver

2016-11-30 Thread Martin Braun
If you change the FFT size, the allocated carriers do not change. Hence, you'll be using a much smaller fraction of your bandwidth. This is by design. As you point out, if you want to occupy more carriers, you have to modify 'Occupied Carriers'. Cheers, M On 11/30/2016 09:49 AM, maiconkis...@gmai

Hi list, I’m messing around with the OFDM Transmitter/Receiver provided by GNURadio to test different configurations (basically I want to increase the throughput, buts thats not the topic of this mail). So, I used the basic ofdm/ofdm_loopback.grc example. First, I run the example with a FFT s

Use a file source block with “short” type into an “Ishort to Complex” block. The Ishort to Complex block will de-interleave the shorts into complex samples. PWG > On Nov 30, 2016, at 8:55 AM, AndroidT Tester > wrote: > > Hey guys, > > I have a sample file with IQ pairs, each I and Q is 16-bit

Hey guys, I have a sample file with IQ pairs, each I and Q is 16-bits, I want to load this in GNURadio companion using File source sink, but I'm not sure how can I specify 16-bit format for I and 16-bit for Q in Gnuradio companion and then connect it to lets say FFT or Waterfall widget. Can someon

Hi Greg - Good to hear from another OS X GR user! I think 1-3 in your list are pretty accurate; I'll add for 3 that it's easy to use MacPorts to do development with GR, either directly inside MP or via OOT modules. I'll add 4: from source! I use a mix of 3 and 4, which with the proper CMake setting

Greetings all, Picked up my first ever OS X machine Friday. I have had tons of success with various flavors of Linux with gnuradio (a massive shout out to the contributors!) Now I see there are a half dozen paths to installing gnuradio on OS X, the big three I found are below. Hopefully havin
