本文先介绍了整个系统的硬件电路设计，而后用VHDL硬件描述语言完成了系统控制程序的编写，并对系统进行了程序仿真及调试验证。本文特别详细的讨论了系统程序的编写，因为他关系到整个系统的功能实现，也是本设计的重点所在。设计中选用Protel 99se作为电路图编辑软件，选用Max+plusⅡ作为仿真环境。(This article first describes the overall system hardware design, then use the VHDL hardware description language, the system control program to complete the preparation, and system simulation and debugging of program verification. This particular system is discussed in detail the preparation process, because he related to the functions of the entire system to achieve, is the focus of this design. Design selected Protel 99se as circuit editing software, use Max+ plus Ⅱ as a simulation environment.)

说明：  小波分解的代码，并且计算出准周期，是一个入门级别的代码，仅供参考。(Wavelet decomposition of the code, and calculate the quasi-periodic, is an entry-level code, for reference purposes only.)

Oqpsk调制与解调matlab源代码，用于在matlab中仿真oqpsk调制与解调的过程，非常适合初学者。(Oqpsk modulation and demodulation matlab source code for the simulation in matlab oqpsk modulation and demodulation process, very suitable for beginners.)

2D-DCT 压缩图像后，通过QPSK,AWGN信道编码传输后，IDCT解压缩回原始图像，适用于任何图像(Using DCT to compress the orginal image, I use zigzag program, quantization, dct compression, then change the vector to bineary bit to pass through the QPSK channel. And from the binary array, I use IDCT to reconstructe the orignial image. working perfectly.)
