In this paper, the dynamic compressing experiments for the matrix material of the tungsten alloys which have been three different deforming(0%、 32.6%、 44.6%) processed have been performed by the experimental technology of separated Hopkinson pressure bar and many accurate datum have been obtained. Also the three materials have been compared with each other and analyzed. The results show that the optimized values are in a certain range to optimize the materials by changing their deforming technology. The parameters of constitutive model of Johnson-Cook have been fitted based on the datum. Then proceed to the next step, adiabatic shear band of these three matrix materials has been analyzed with finite element method. The result shows that the relations between stress and strain are different because of the differences of technical process of the three materials, but they are in great commonness in the material experiment and in great coherence in the distribution of time and space, which can been seen from the space distributing figures of plastic strain.

利用分离式Hopkinson压杆实验技术对三种不同变形量(0%、32.6%、44.6%)钨合金基体材料进行动态压缩实验，取得大量精确的数据，对比分析三种材料，结果表明通过改变变形量对材料进行优化，其变形量的优化值是有一定范围的；本论文拟合、确定了钨合金基体材料Johnson-Cook本构模型参数并对三种基体材料绝热剪切带进行有限元分析，结果表明三种材料由于工艺流程的不同，应力应变关系也不尽相同，但从塑性应变的空间分布图上体现了材料很大的共性和时间以及空间分布的一致性。

Firstly the basic principle of OFDM and its anti-multi-path-fading are briefly introduced in this paper. Then basing on this point, we researched the basic principle, the coding designing and the algorithm of the signal detection of these MIMO-OFDM systems. At the same time, the performances of STBC-OFDM and SFBC-OFDM were analyzed and simulated under short wave circumstance, and got some useful conclusions, they have certain reference value for more research of short wave communication in future.

本文首先介绍了OFDM系统的基本原理以及它对抗多径的基本原理，然后在此基础上，对其所形成的几种MIMO-OFDM系统的基本工作原理，码字设计以及相应的信号检测算法进行了研究，详细分析研究了STBC-OFDM和SFBC-OFDM系统的性能并在短波信道下对其性能进行了仿真和对比分析，得出了有用的结论，这对以后短波通信的深入研究具有参考价值。
