[Discuss-gnuradio] Bits inserted at random places

2017-08-09 Thread 李博远
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

Sean - OK, I understand what you mean now, thank you - the overflow is not reported until the pressure hits the source block. Cinaed - In this case it is not my flowgraph but gnss-sdr which I've run successfully on several platforms. In this case it is running on a Raspberry Pi 3. I anticipate

[Discuss-gnuradio] Explanation on how the preamble is inserted and how the packet is detected

Hi Ricardo, the "Comprehensive GNU Radio Archive Network", cgran.org, is your friend :) When you look for "encryption" there, you'll find gr-nacl (thanks to its author, Stefan Wunsch). It uses the rather established NaCl library; it should cover your cryptographic needs! Best regards,

[Discuss-gnuradio] Encryption

2017-08-09 Thread Ricardo Nuszkowski
Hello, I am building a ground station for my university and we are going to be using a LimeSDR and GNU radio. I was wondering what type of encryption is available with GNU radio. We were looking to see if it handles AES 256 or NSA type 1 encryption. Respectfully, Ricardo
