Due to its ease of implementation, intensity modulation with direct detection (IM/DD) based on ON–OFF keying (OOK) is a popular signaling scheme in these systems. Over turbulence channel, to detect OOK symbols in a blind way, i.e., without sending pilot symbols, an expectation–maximization (EM)-based detection method was recently proposed in the literature related to free-space optical
On-off keying (OOK) denotes the simplest form of amplitude-shift keying (ASK) modulation that represents digital data at the presence or absence of a carrier wave. In its simplest form, the presence of a carrier for a specific duration represents a binary one, while its absence for the same duration represents a binary zero.
Amplitude shift keying (ASK) is a very popular modulation used in control applications. This is due to its simplicity and low implementation costs. ASK modulation has the advantage of allowing the transmitter to idle during the transmission of a bit zero. Therefore this reduces the power consumption. This disadvantage of ASK modulation arises in the presence of an undesired signal. in

Binary Amplitude Shift Keying (BASK) or On Off Keying (OOK) is one of the digital modulation techniques in which the amplitude of carrier is switched according to the binary data. This digital modulation scheme is used to transmit digital data over optical fiber, point to point military communication applications, etc. Binary 1 is represented by a short pulse of light and binary 0 by the

On-Off Keying Modulation and Tardos Fingerprinting
The simplest form of DM represents a series of logical ‘1’s and ‘0’s by simply switching on and off the carrier. For this reason it is often called On-Off Keying (OOK). (The term ‘keying’ goes back to the days of ‘Morse Code’ when transmissions were switched on and off by hand, using
