频率的测量实际上就是在1s时间内对信号进行计数，计数值就是信号频率。用单片机设计频率计通常采用两种办法，第一种方法是使用单片机自带的计数器对输入脉冲进行计数；第二种方法是单片机外部使用计数器对脉冲信号进行计数，计数值再由单片机读取。-In the measurement of frequency is actually 1s to count time signal, numerical is signal frequency. Using single-chip microcomputer f

Multiple input multiple output techniques combined
with orthogonal frequency division multiplexing (MIMO-OFDM)
provide a promising approach for wireless systems. However, a
serious drawback of the OFDM system is the high peak-toaverage

基于FPGA的单精度浮点数乘法器设计，本文设计了一个基于FPGA的单精度浮点数乘法器。乘法器为五级流水线结构。设计中采用了改进的带偏移量的冗余Booth3算法和跳跃式Wallace树型结构，减少了部分积的数目，缩短了部分积累加的耗时；提出了对尾数定点乘法运算中Wallace树产生的2个伪和采用部分相加的处理方式，有效地提高了的运算速度；并且加入了对特殊值的处理模块，完善了乘法器的功能。单精度浮点数乘法器在Altera DE2开发板上进行了验证，其在Cyclone II EP2C35F672C6器

对于系统单参数分岔图的计算共有以下的几种方法：
1）最大值法
即对系统微分方程（组）进行求解，对求解的结果用getmax函数进行取点，并绘图。
2）Poincare截面法
对系统参数的每一次取值，绘制其Poincare截面，进而得到其分岔图。
这种方法需要注意的是，自治系统的Poincare截面是选取一超平面，平面上点的分布即构成一Poincare截面，非自治系统的Poincare截面则是根据系统激励的频率进行取点并绘图。(There are several
