s that are
scrambled with the "Additive Scrambler" block?Do I have to write my own block?
Thank youDaniel

Hi,I want to use the scrambling polynomial: 1 + X^12 + X^17. This means the
currentlytransmitted bit is the EXOR of the current data bit, plus the bits
thatwere transmitted 12 and 17 bits earlier.But I'm not sure what are the
suitable values for Mask and Seed for the gnuradio Scramble Block.Any

Hi,
I read in the documentation that HDLC framer takes in PMT binary blobs and
outputs HDLC frames as unpacked bits.I don't undestand what are the PMT binary
blobs.How can I put in an HDLC frame a "Hello World" message?
ThanksDaniel

Hi,
How to tell my receiver to identify a specific packet through a received bit
stream?
I transmit a custom packet (with header, payload, crc16).
Is there any block in gnuradio that I can use for this purpose?
I had a look on "Packet Header parser" and "parser sink" blocks, but I did't

Hi
I derive the output of a signal, both to an Interpolating FIR filter and
Rational Resampler (in parallel) and then I connect them to a Time Sink (with 2
inputs).
I use the same interpolation factor for both blocks (interpolation = 4).
I also use in taps the same rcc filter.

Thank you all for your help!
As Marcus suggested, by passing the "-DCMAKE_CXX_FLAGS=-ludev" in cmake, I
managed to solve the problem.
I report here the output of the command "pkg-config --static --libs libusb-1.0":
-pthread -lusb-1.0 -lrt
and the output of the command: "ldd lib/libgnuradio-fcd

I use ubuntu 12.04 and libusb-1.0-0-dev
Do you what version of libusb is compatible?___

Hi,
do you know if the default PSK Demodulation block does any frecuency correction
or time recovery?
After running some tests, I have noticed that when I use a Channel Model
between PSK mod and PSK demod, I successfully decode my data even I have a
small frecuency offset or time offset (Epsilo
Hi,
I have installed GNU Radio Companion 3.7.5 and the gr-fcdproplus from
dl1ksv/gr-fcdproplus (GitHub).
By simpy connecting the fcdproplus block with an fft sink I receive the
following error:
