psk调制与解调（加入噪声）。属于通信原理的课程设计。-psk modulation and demodulation (add noise). Communication Theory belong to the curriculum design.

MATLAB课程设计。AM调制与相干解调系统仿真。-MATLAB curriculum design. AM modulation and coherent demodulation system simulation.

基于matlab的2fsk的调制与解调源程序，以及眼图，误码率的计算，相干解调，非相干解调的比较-Matlab-based 2fsk the source of the modulation and demodulation, as well as the eye diagram, bit error rate calculation, coherent demodulation, comparison of non-coherent demodulation

在带通采样条件下实现了QPSK信号的调制解调，并附有每一步的曲线图- U5728 u901A u901A u91C0 u6837 u673 u4E09 u4E0B u5B9 u3B0 u4E86QPSK u4FE1 u53F7 u7684 u8C03 u5236 u89Y3 u8E03 uFF0C u5E76 u9644 u6649 u6BCF u4E00 u6B65 U7684 u66F2 u7EBF u56FE
