I really need some help in making custom blocks with input/outputs of variable
data types.
Has anybody done this before? Any Tutorial/Link?
Regards.
Ahmed.

When you go to the GNU Radio website, then navigate to the tutorials
section, there's a tutorial How to design a signal processing block
with variable types of inputs or outputs.
It's a bit outdated, but really not hard to find.

Hi,
I would like to announce a paper I published few months ago with
some friends on a DCSK chaotic modulation implementation with GNU
Radio. The full reference is:

Hello all,
I am doing my senior design project on cooperative spectrum sensing. I have
already done the theortical design and matlab simulation for the system. Now, I
want to implement this on a hardware. I want to use gnu radio and usrp. Does
anyone know a good place to start? or any
Hi all,
I am working on a custom block that tags a stream based on a binary file
stretched into unpacked form:
(1) (2)(3)
gr_file_source(repeat=false) -- gr_packed_to_unpacked(1, gr.MSB_FIRST) --
my_block
I want to come up
Is it possible to use a vector input or output with a block that uses
the GRExtras interface? All of the examples for specifying the I/O
signature for a Python block only show using a numpy type to specify
the data width.
I also tried creating a C++ block and setting the sizeof_stream_item

Hi, I am currently doing channel sounding on USRP N210. There is an
example of sounder in the old release 3.4. However, it is designed for
usrp1. I am reading its fpga code and trying to follow its work flow.
When doing grc based channel sounding, i can not work at a high
sampling rate. Also my

Hello Josh,
Thanks for the suggestion. Yes I had zero padded the file with about 1
second of zero signal prior to the signal I want to transmit. I had still
seen the blip/noise when running the script even when there was 1 second of
