Thanks, i did not know this rule about complex samples.

Ok thanks.

I'm a bit confused by your calculation. Nyquist for complex data is equal to
the analog bandwidth so you only need a sample rate of 25.6 MSPS as stated. USB
3.0 will handle this without a problem on the B200. If you use short (16 bit
integers) IQ then you have 4 bytes/complex sample so ~100MB/se

What about an RFNoC solution?

128 channels of
Hi,
I need to decode about 128 channels at the same time
Details are:
2-GFSK modulation, 25khz devation, channel separation is 200khz
It seems like a perfect fit for a poly phase filter - however this is
something that I believe needs to be done in hardware (128 channels *
200khz = about 60mh
Hi,
I've captured some data - and I am trying to decode this at a packet
level.
I am confused about the "binary slicer" - and how to do stuff with it.
What I am expecting ... and looking for is this:
The transmission is FSK, baud rate: 50K, Modulation GFSK (+/- 25khz),
The data packets look l
Hi Gabriel,
I think this block may be scheduled for deprecation... You May want to
look at the Correlation Estimator block instead.

Hi all,
I wanted to know how to use correlate access code block, if there is a
example it will be usefull.
I am tring to use it to syncronize bits in reception.
Thank you all

Hi,
I've found this post related to my problem:
http://lists.gnu.org/archive/html/discuss-gnuradio/2015-02/msg00277.html
So, I've tried the following:
1) Derive a class from ofdm_equalizer_base
2) Add the function get_base_ptr() to the derived class. This function
returns a pointer to the deriv
