Was (wer) ist PSK - definition

WIKIMEDIA DISAMBIGUATION PAGE
PSK (disambiguation); Psk

PSK         
<communications> Phase Shift Keying.
PSK         
Phase Shift Keying (Reference: telecommunication)
BPSK         
  • Constellation diagram for 8-PSK with Gray coding
  • [[Constellation diagram]] example for BPSK
  • Timing diagram for DBPSK and DQPSK. The binary data stream is above the DBPSK signal. The individual bits of the DBPSK signal are grouped into pairs for the DQPSK signal, which only changes every ''T<sub>s</sub>'' = 2''T<sub>b</sub>''.
  • BER comparison between DBPSK, DQPSK and their non-differential forms using Gray coding and operating in white noise
  • BER comparison between BPSK and differentially encoded BPSK operating in white noise
  • Differential encoding/decoding system diagram
  • Timing diagram for offset-QPSK. The binary data stream is shown beneath the time axis. The two signal components with their bit assignments are shown the top and the total, combined signal at the bottom. Note the half-period offset between the two signal components.
  • Difference of the phase between QPSK and OQPSK
  • Bit-error rate curves for BPSK, QPSK, 8-PSK and 16-PSK, additive white Gaussian noise channel
  • Mutual information of PSK over the AWGN channel
  • Dual constellation diagram for π/4-QPSK. This shows the two separate constellations with identical Gray coding but rotated by 45° with respect to each other.
  • Timing diagram for π/4-QPSK. The binary data stream is shown beneath the time axis. The two signal components with their bit assignments are shown the top and the total, combined signal at the bottom. Note that successive symbols are taken alternately from the two constellations, starting with the "blue" one.
  • Signal doesn't pass through the origin, because only one bit of the symbol is changed at a time.
  • Constellation diagram for QPSK with [[Gray coding]]. Each adjacent symbol only differs by one bit.
  • Timing diagram for QPSK. The binary data stream is shown beneath the time axis. The two signal components with their bit assignments are shown at the top, and the total combined signal at the bottom. Note the abrupt changes in phase at some of the bit-period boundaries.
  • Receiver structure for QPSK. The matched filters can be replaced with correlators. Each detection device uses a reference threshold value to determine whether a 1 or 0 is detected.
  • Conceptual transmitter structure for QPSK. The binary data stream is split into the in-phase and quadrature-phase components. These are then separately modulated onto two orthogonal basis functions. In this implementation, two sinusoids are used. Afterwards, the two signals are superimposed, and the resulting signal is the QPSK signal. Note the use of polar [[non-return-to-zero]] encoding. These encoders can be placed before for binary data source, but have been placed after to illustrate the conceptual difference between digital and analog signals involved with digital modulation.
