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

- 基于复数概念的正交信号，对于DSP的初学者而言，可能没有什么比j算子、复数、虚部、实部和正交等数据及概念更令他们头痛的了。如果你对复数和1j − 的物理含义不是那么明确的话，不必感到懊恼，因为你有很好的同伴。为何甚至是世界上最伟大的数学家之一的卡尔·高斯都曾经说过，虚数j算子是“虚幻的幻影”。本文将对这个“幻影”做出一些解释，这样，你就不必打电话到“正交信号心理咨询热线”寻求帮助了。-Quadrature signals are based on the notion of compl
