[Discuss-gnuradio] Re: transmitter code

[harshal jadhav]

Hi Eric,

I have a few questions regarding MIMO + GNU RADIO.

1. How can i use MIMO with GRC?

If i use one USRP sink, it considers one whole USRP board. I cannot use two daughter boards of the same USRP board using USRP sink.

2. In gnuradio-examples/python/usrp/fm_tx_2_daughterboards.py  can i use flex 900 boards?

I have tried implementing the example with the flex 900 board but it shows more of noise. I changed the sinusoid signal frequency to 4000 Hz and 10000 Hz. While running the code it asks for carrier frequency for both the signals. I have given the frequency to 900 MHz.

REGARDS,
HARSHAL JADHAV

Please have a look at
