QPSK通信调治与解调DSP开发C++代码，可以在TI DSP上实现-QPSK modulation and demodulation communications DSP development of C code can achieve TI DSP

qpsk调制程序，经本人在dsp上实验，完全可以实现-qpsk modulation procedure, I dsp on the experiment, can be completely achieved

qpsk解调，经本人在dsp上实现完全可以使用-qpsk demodulation, I fully realize dsp can use

This setup illustrates the principle of coherent detection and digital signal processing (DSP) for a coherent 112Gb/s QPSK signal. The system performance is limited by noise (added in front of the receiver), chromatic dispersion and PMD (taking place
