Description: 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QPSK调制解调的基本原理，并使用MATLAB编程实现QPSK信号在高斯信道和瑞利衰落信道下传输，以及该方式的误码率测试。复习MATLAB编程的基础知识和编程的常用算法以及使用MATLAB仿真系统的注意事项，并锻炼自己的编程能力，通过编程完成QPSK调制解调系统的仿真，以及误码率测试，并得出响应波形。在完成要求任务的条件下，尝试优化程序。 通过本次实验，除了和队友培养了默契学到了知识之外，还可以将次实验作为一种推广，让更多的学生来深入一层的了解QPSK以至其他调制方式的原理和实现方法。可以方便学生进行测试和对比。足不出户便可以做实验。
