  2. Phase-shift keying - Wikipedia

    en.wikipedia.org/wiki/Phase-shift_keying

    Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency carrier wave. The modulation is accomplished by varying the sine and cosine inputs at a precise time.

    en.wikipedia.org/wiki/Polysaccharide-K

    PSK is a protein polysaccharide consisting of a beta-glucan β-1,4 main chain with β-1,3 and β-1,6 side chains. The approximate molecular weight of PSK is 100,000 Da, and the protein component is reported at the β-1,6 side chain. [10] PSK is isolated from the "CM-101" strain of Trametes versicolor.

    A waterfall display depicting several PSK31 transmissions at around 14,070 kHz. The green lines indicate a station that is transmitting. PSK31 or "Phase Shift Keying, 31 Baud", also BPSK31 and QPSK31, is a popular computer-sound card-generated radioteletype mode, used primarily by amateur radio operators to conduct real-time keyboard-to-keyboard chat, most often using frequencies in the high ...

    en.wikipedia.org/wiki/Polysaccharide_Peptide

    Polysaccharide krestin (PSK) was first isolated in Japan in the late 1960s while PSP was isolated about 1983 in China. Each compound has shown remarkable anticancer properties with few side effects. [2] By 1987 PSK accounted for more than 25% of total national expenditure for anticancer agents in Japan. [3]

  8. Minimum-shift keying - Wikipedia

    en.wikipedia.org/wiki/Minimum-shift_keying

    In digital modulation, minimum-shift keying (MSK) is a type of continuous-phase frequency-shift keying that was developed in the late 1950s by Collins Radio employees Melvin L. Doelz and Earl T. Heald. [1]

  9. TLS-PSK - Wikipedia

    en.wikipedia.org/wiki/TLS-PSK

    TLS-PSK uses symmetric keys, shared in advance among the communicating parties, to establish a TLS connection. There are several reasons to use PSKs: Using pre-shared keys can, depending on the ciphersuite, avoid the need for public key operations. This is useful if TLS is used in performance-constrained environments with limited CPU power.
