Signals intelligence (SIGINT) is intelligence-gathering by interception of signals, whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management.
As sensitive information is often encrypted, signals intelligence often involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to derive information.
Electronic interception appeared as early as 1900, during the Boer Wars. The Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s and some limited wireless signalling was used by the British Army. Some wireless sets were captured by the Boers, and were used to make vital transmissions. Since the British were the only people transmitting at the time, no special interpretation of the signals that were intercepted by the British was necessary.
BAE Systems' series of high-performance SIGINT systems analyze electronic signals to provide insight into adversaries' plan of action. Learn more at http://www.baesystems.com/sigint
The workshop will cover many common techniques used to reverse engineer the physical layer of a wireless communications system: - Blind signal analysis on a signals re-broadcast from a satellite transponder: modulation type, order, symbol rate, error correction,scrambling, differential coding, visualization - Applying auto-correlation to interesting signals on the HF band: RADAR, OFDM, symbol timing - Frequency hopping: wide-band, real-time spectrum visualization All with GNU Radio! Participants are advised to bring their own SDR to receive signals with, and have the very latest version of GNU Radio installed, and if they can manage also the gr-baz out-of-tree module. Signal fundamentals Properties that can be exploited for blind signal analysis Modulation schemes Periodicity in symbols ...

In the season, the month of April, the song written on sand vanishes.
At the bottom, it is a dark and endless tomorrow. to meet, to say goodbye under the blue sky.
The end of summer, I met the sea.
What is love if it just drifts away and it's gone?
What did I pray to the sun that I know I can't reach, and turn it to ashes?
I can't seem to end it,
so again I pick up the pieces of you that disappeared in the sand.
He sings the song written on the sand with his head down,
keeping his voice down, and underneath it...
The tears from the sky hit me. Everyone looks so happy.
You are not here by me on my left side. The breeze is in blue from last year.
I met you in early autumn.
The weight of sadness more then the weight of the pain.
Flowers blooms and flowers fall, but a flower is as it is a flower.
But also wish to change by tomorrow.
