Examples in Context

  1. The performance estimation of quadrature phase shift keying ( QPSK ) signaling over a Rice lading channel was simulated and the corresponding analyzing results were obtained.
  2. Feher patented Quadrature Phase Shift Keying(QPSK) ( FQPSK ), which is suitable for deep space communication, is introduced at first.
  3. IJF-OQPSK is actually to modulate the IJF codes by the Offset Quadrature Phase Shift Keying(QPSK).
  4. For quadrature phase shift keying ( QPSK ) modulation technique, a baseband DBF algorithm of smart antenna fixed beams is presented.
  5. In order to make the limited spectrum range accommodate more communication channels, some linear modulation techniques are proposed, such as QAM ( Quadrature Amplitude Modulation ), QPSK ( Quadrature Phase Shift Keying(QPSK) ), etc.
