The authors show that the predicted signal-to-noise ratio (SNR) for BPOLSK and NRZ-OOK schemes are ∼13.5 and ∼15 dB, respectively, for a BER of 10−6 and σ21 of 0.01.

On–off keying (OOK) denotes the simplest form of amplitude-shift keying (ASK) modulation that represents digital data as 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. Some more sophisticated schemes vary these durations to conve… Web6 de jul. de 2014 · A hybrid 2 slots binary phase shift keying-on off keying (hybrid 2BPSK-OOK) scheme is proposed as a new modulation technique to improve the performance of both conventional binary phase shift ...
WebOn-Off Keying (OOK) On-off keying (OOK) is a modulation scheme that consists of keying a sinusoidal carrier signal on and off with a unipolar binary signal. OOK is equivalent to two-level amplitude-shift keying (ASK). Unipolar Binary Baseband Signal. Resulting OOK Modulated Signal. previous page start next page.
