how to install your gnuradio

[sunwit]

hello, when i manually install gnuradio from your repository, i did make test, but it is stuck at the following test: 300/356 Test #300: qa_ofdm_frame_equalizer_vcvc ....................... Passed 0.33 sec Start 301: qa_vblast_loopbac

dear author,

after i omit the make test process, my gnuradio can work. but, the ofdm receiver or transmitter does not have mimo features.

@sunwit MIMO is not yet part of the main GNU Radio Tree, as you can see the open PR here https://github.com/kit-cel/gnuradio/pull/32. You can either check out that development branch or wait until it is merged into master. This work will probably be upstreamed to the original GNU Radio repository, but a certain date or time range for when that might happen is something that can't be promised.

Have a look at the documentation here: https://github.com/kit-cel/gnuradio/pull/32

@sunwit The PR that I references regards only the channel estimation, not the Tx-Rx. Sorry about that. A quick look at the code suggests that the MIMO-OFDM receiver and transmitter block is under construction in the https://github.com/kit-cel/gnuradio/commits/mimo_hier_block branch. I believe it is just safer to assume that this feature is not yet available, and therefore there is no real issue to be reported.

Thanks @primercuervo for clearing that up! The https://github.com/kit-cel/gnuradio/commits/mimo_hier_block branch includes indeed the current development of the MIMO-OFDM. So if you want to check it out: The MIMO-OFDM transceiver is already working without sync, and I am implementing the sync functionalities at the moment (actually it is finished but not fully tested, yet).

Thanks @primercuervo @MoritzLucaSchmid for explanation.
