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。s
(This is an original SOQPSK modulation process, the clarity, Approach. Matlab language used to write and SOQPSK is an uncommon, more cutting-edge modulation and demodulation. The routine is successfully used matlab language to implement SOQPSK modulation, and draw out SOQPSK time-domain waveform, the phase diagram, spectrogram, power spectral density maps, easy for beginners to learn to use. s)
