QPSK编码的DSP实现
- 四相相移键控信号简称“QPSK”。它分为绝对相移和相对相移两种。由于绝对相移方式存在相位模糊问题,所以在实际中主要采用相对移相方式QDPSK。它具有一系列独特的优点,目前已经广泛应用于无线通信中,成为现代通信中一种十分重要的调制解调方式。 QPSK是英文Quadrature Phase Shift Keying的缩略语简称,意为正交相移键控,是一种数字调制方式。在数字信号的调制方式中QPSK四相移键控是目前最常用的一种卫星数字信号调制方式,它具有较高的频谱利用率、较强的抗干扰性、在电路上实现也较
毕业设计基于matlab的QPSK系统仿真
- QPSK是英文Quadrature Phase Shift Keying的缩略语简称,意为正交相移键控,是一种数字调制方式。在19世纪80年代初期,人们选用恒定包络数字调制。这类数字调制技术的优点是已调信号具有相对窄的功率谱和对放大设备没有线性要求,不足之处是其频谱利用率低于线性调制技术。19世纪80年代中期以后,四相绝对移相键控(QPSK)技术以其抗干扰性能强、误码性能好、频谱利用率高等优点,广泛应用于数字微波通信系统、数字卫星通信系统、宽带接入、移动通信及有线电视系统之中......理解QP
