该算法实现了OPSK的调制解调功能，非常全面。从编码到调制、解调、信道估计、载波频偏和相骗的估计等等。非常具有代表性，可作为课程设计和实际的工程应用等。-The algorithm implements OPSK modem functions, very comprehensive. From coding to modulation, demodulation, channel estimation, carrier frequency offset and phase estimation and so cheated. Very representative, as curriculum design and practical engineering applications.
