Re: [Discuss-gnuradio] about tune the daughterboard

Thanks. Eric. And you've had a good vocation, haven't you?

 

The GMSK2 code works well and the way of tuning at transmit_path and receive_path is OK.

 

For single channel,

    In the transmit_path:

        self.u.tune(self.subdev._which, self.subdev, target_freq)

    In the receive_path:

        self.u.tune(0, self.subdev, target_freq)

is all right.

 

How about double channel, for example, a 2 x 2 MIMO. I guess 2 Flex 2400 are need on transmitter (2 TX/RX) and 1 for receiver (RX2 and TX/RX as RX). How about the tunning?

 

transmitter:

    self.u.tune(self.subdev1._which, self.subdev1, target_freq)

    self.u.tune(self.subdev2._which, self.subdev2, target_freq)

 

receiver:

    self.u.tune(0, self.subdev, target_freq)

    self.u.tune(1, self.subdev, target_freq)

 

If this way is OK? I haven't implement the MIMO yet, just want to understand it before I do so.
