介绍qpsk调制的代码！初学者可以参考参考！比较简单.,Introduction QPSK modulation code! Beginners can refer to reference! Relatively simple.

该程序完成QPSK从比特到符号的映射，其中XY_in_en为输入的比特使能信号，XY_data为IQ合路后的输入比特数据。I_out和Q_out为映射后的符号对。-Completion of the program from the QPSK mapping bits to symbols, in which input bits XY_in_en enable signal, XY_data for IQ Combiner bit after the data input. I_out and

基于VHDL硬件描述语言---对基带信号进行MPSK调制（这里M=4）,即QPSK调制-asfgsfagsdgfhergew

通过MATLAB对QPSK进行仿真，再在FPGA中实现QPSK的基本功能-By MATLAB simulation of QPSK, and then in the FPGA to implement the basic functions of QPSK
