What is offset in QPSK?
Offset QPSK, which involves adding a delay to one of two digital data streams used in the modulation process, reduces the maximum phase jump to 90°. Another option is π/4-QPSK, which reduces the maximum phase jump to 135°.
What is the difference between QPSK and offset QPSK?
Offset Quadrature Phase Shift Keying (OQPSK) is a variant of the QPSK modulation scheme where the phase or timing of either the in-phase or Quadrature component is shifted relative to each other by a one bit-period or half a symbol-period Ts as compared to QPSK.
What is the advantage of offset QPSK compared to the conventional QPSK?
From the obtained results it can be concluded that OQPSK performs better than QPSK modulation in terms of BER, which indicates that OQPSK has a better bandwidth efficiency and hence it can be used for systems with less power since it has a better channel frequency error.
What is OQPSK?
Offset quadrature phase-shift keying (OQPSK) is a variant of phase-shift keying modulation using four different values of the phase to transmit. It is sometimes called staggered quadrature phase-shift keying (SQPSK).
