[Discuss-gnuradio] integral frequency shift correcting in ofdm_frame_equalizer_vcvc_impl.cc

2014-09-02 Thread Tiankun Hu
Hi All, I found ofdm_frame_equalizer_vcvc_impl.cc use below code to correct integral freq shift(IFO) in freq domain, but as I known, the IFO only cause signal cyclic shifting in freq domain, why this block use gr_expj to correcting IFO in freq domain? might be blow code should be done in time

Tiankan, this corrects the coarse freq offset propagation due to the CP. As 'i' increments, this represents later times. So, in a sense, this is in time direction. M On 09/02/2014 04:14 PM, Tiankun Hu wrote: Hi All, I found ofdm_frame_equalizer_vcvc_impl.cc use below code to correct integral

The best way to use the .cmake files installed by GNU Radio in an OOT module is to do the {{{ find_package(Gnuradio [...]) }}} as close to first thing as possible. Once that's done, then all of the other GR .cmake modules (including FindCppUnit.cmake) will become available when using CMake =

[Discuss-gnuradio] PSK demodulator and Doppler

2014-09-02 Thread Mike Willis
I am trying to develop a satellite ground station using the PSK demodulator block. This works fine when tuned accurately. However, with low satellites there is quite a bit of Doppler at VHF / UHF and there is also some frequency drift with satellite temperature as it enters or comes out of

Hi all, I have the following flowgraph: [image: Inline image 2] I want to interrupt the whole flowgraph to back to the main function (C++). I used to return -1 or WORK_DONE in the work function of the sink block but it doesn't work. What is the solution? Thanks in advance, Mostafa
