中文说明：这是一个原创的SOQPSK调制程序，条理清晰，思路简介。使用了matlab语言书写，且SOQPSK是一种不常见的、比较前沿的调制解调方式。本程序即成功的使用matlab语言实现了SOQPSK的调制，并绘制出了SOQPSK的时域波形图，相位图，频谱图，功率谱密度图，便于初学者学习使用。
English Description：
This is an original SOQPSK modulation process, clarity of ideas about. Use the MATLAB language, SOQPSK is kind of unusual, advanced modulation and demodulation. Using MATLAB to realize the success of this program, SOQPSK, modulation, and draw out the time domain waveforms of SOQPSK, phase diagram, spectrogram, power spectral density, easy for beginners to use.
