Hi, All,
I try to reinstall gnuradio (3.5.0rc0) on E100 with
$ cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/arm_cortex_a8_native.cmake
../
$ make
I got errors when build gruel.
How can I fix it?
Before this, I got errors for unidentified gcc when cmake, so I
opkg remove gcc

Hi,
What is the difference between the effect of channel model taps of [1,0]
(i.e. 1+j0) and [1,1] (i.e. 1+1j) have in the output? Frequency offset and
epsilon=1.0 in both cases.
Thanks

I recommend cleaning out old installations before reinstalling gnuradio.
Not doing so has caused many problems.

Interesting. Thanks.
Do you know why the do it? Do they just have the filter on one side?

PSK31 for ham radio uses a raised cosine filter rather than the RRC.

Ok, but my question was Why do you need a raised cosine filte
Hey list,
I have noticed that many user's have found the need to mux a stream.
Either to dynamically select an alternative data source or to mux an
output to an alternative sink like a different demodulator.
Currently, GRC has come with selector (and valve). These blocks
implement stream muxing b
Hello, as some of you may know I recently installed a fresh GNURADIO

Because I need a raised cosine filter. If I convolve root raised cosine filter
coefficients with themselves (generated with gr_firdes), do I need to apply a
scaling factor?

Dear Josh,
Thanks for your reply. Does this mean that there is no method to implement
the C++ recv and stream commands using an absolute start time in the
currently implemented gnuradio python api?

Bill,
Automatic Modulation Classification (AMC) is still a heavily researched
area, and you should be able to find hundreds of papers on the topic by
searching IEEE for 'automatic modulation classification'. There are
algorithms that use energy analysis, imaging techniques, cyclostationarity

Hello,
thanks for the help.
