Hi,
I'm testing the basic packet transmission functions.
I use a vector source to generate binary stream, tag it, add crc, use a
protocol formatter to generate a header and mix the header with the
payload.
On the receiver end, I use a correlation estimator to do packet
detection, and
tect the packet at the receiving end once it is

Hi,
I have implemented BPSK and OFDM in GNURadio. They are modified from the
examples given, just without those crc32 modules. They work well in
GNURadio.
However, when I test the programs on the hardware, USRP x310, a problem
emerges. I found that often than not, there are some extra bits in my
Hi Adhitha,
Just check out the examples in the folder
