quadrature phase shift keying

基本解釋

Offset Quadrature Phase Shift Keying?
偏移量正交相移鍵控 OQPSK?。
IJF-OQPSK is actually to modulate the IJF codes by the Offset Quadrature Phase Shift Keying.
OQPSK實(shí)際上是對(duì)IJF信號(hào)再進(jìn)行正交四相相移鍵控的調(diào)制技術(shù)。
And an all-optical regenerator design scheme for quadrature phase-shift keying(QPSK) and differential quadrature phase-shift keying(DQPSK) signals was investigated through numerical simulations.
對(duì)適用於正交相移鍵控和差分正交相移鍵控信號(hào)的全光再生器進(jìn)行了倣真。
