QDPSK方面的仿真，可以供大家学习参考，还不错，可以看看，仅供参考(QDPSK aspects of simulation, everyone can learn reference, well, you can see, for reference purposes only)

OFDM第一版（经典课件）有大量详细的关于OFDM的讲解(OFDM first edition (the classic courseware) a large number of detailed explanation on the OFDM)

谢菲尔德大学遗传算法工具箱,非常实用,是遗传算法的典范(University of Sheffield, genetic algorithm toolbox very useful, is a model of genetic algorithm)

是数模方面的一个很好资料,它为数模参赛者提供一个好的引导.(few die of a good information, it will provide participants with the number die a good guide.)

以SUVM迭代直接求解出观测值的改正数，给出一个简单算例，以资验证。 (The correction of the observation is obtained by the interation with gradient projection method and a simple calculation example is given to verify it)
