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:
se
Isn't the way this works that the USRP disconnects/reconnects after the
firmware download? Maybe the Mac misses that somehow? What happens if
after loading the firmware you unplug and reconnect the USB?
Cheers,
Jan

which are needed? Any other Intel-mac users see this?
Works fine

Hi,
Recently, I'm trying to do CDMA commnication at 1.28Mchip/s with USRP and I've met a problem.
The sample rate of DAC on USRP is 128M, so samples avialabe for each chip is 128M / 1.28M = 100.
The interpolation rate of USRP must be [4, 512] and multiple of 4. So the only choice for me seems to

Hi,
I started developing with GNU Radio a couple of weeks ago and have been
following the list for a while. I must thank Eric, Matt and everyone else for
all the time they are devoting to this project. Now with my problem...
I am trying to do something which should be pretty simple. I have star

I agree, we should not automate this, though a note in a "how to
install on a macbook" would be nice since a lot of people don't know
about that option.

No I am not. At the time I wrote the post, I didn't think I needed it
since my pulses came back looking pretty good except for the whole
"positive values only" thing. However, my data looks a lot better

I have a few questions related to the scalability of GNU Radio. Any insight
would be most appreciated.
1) I am unfamiliar with IPC, but understand how it could be useful to
increase computing power. What would be the first step in setting it up to
do distributed computing with GNU Radio?
