[USRP-users] RFNoC: Synthesizing a block containing modules from uhd-fpga

2018-01-10 Thread Adam Parower via USRP-users
Hello everyone, I am trying to create a custom RFNoC block that is similar to the built-in DUC block. As such, it depends on the cordic_timed, axi_rate_change, and duc modules defined in uhd-fpga/usrp3/lib/rfnoc. When I attempt to run the testbench for my block, Vivado fails in synthesis. Whil

Dear Nicolas, Many thanks for your reply! Regarding your question, yes, they need to run simultaneously, however, both modules (MIMO PHY and Spectrum Sensing) have different sampling rates. The MIMO PHY will be LTE-based and it will have its BW configured at runtime. I plan to support all the LT

Hello Ale, That left shift is intentional behavior. Here is the comment on that line of code. https://github.com/EttusResearch/uhd/blob/maint/host/include/uhd/utils/soft_register.hpp#L100 When you say you "tried to run query_gpsdo_sensors, that one was not finalized" do you mean that it was not c

Hi folks, I'm worried about something; while maiking the UHD, it ran across something that looked like an error: [ 22%] Building CXX object lib/CMakeFiles/uhd.dir/usrp/multi_usrp.cpp.o In file included from /home/ents622/workarea-uhd/uhd/host/lib/usrp/multi_usrp.cpp:29:0: /home/ents622/workarea-u

Follow-up to my previous post: Hi again, folks, When I followed instructions to make both the UHD and the GNURadio, I got a slew of warnings. Later I ran the GnuRadio test and got one error: 99% tests passed, 1 tests failed out of 212 Total Test time (real) = 140.04 sec The following tests FAILED

Dear Felipe, Are the MIMO PHY and the sensing module required to run simultaneously? If yes, then you could split the streams after receiving (if using RFNoC, you can use the RFNoC: Split Stream block) to divide the streams and process one of them while sending the other to the host. If simultane

Dear All, I'm planning to put together a system composed of a MIMO physical layer and a spectrum sensing module. For this task I will be using one x310. The spectrum sensing module will be implemented on FPGA and will apply an algorithm to the received IQ samples and output a vector with 128 valu
