一种实现电磁波的FDTD仿真模拟的源程序代码(An FDTD simulation of electromagnetic waves of the source code)

matlab 应用数学工具箱的使用，包括概率统计、偏微分方程等。(matlab toolbox of applied mathematics, including probability and statistics, such as partial differential equations.)

OFDM到AFDMA的映射（matlab）(OFDM to AFDMA mapping (matlab))

信号与系统软件实验工具箱，本系统包括七个实验，分别是：信号的时域基本运算、连续信号的卷积与连续时间系统的时域分析、离散信号的卷积与离散时间系统的时域分析、信号的频域分析、连续信号的采样与恢复、系统的频域分析、信号的幅度调制与解调。为了加强学生的计算机编程能力和应用能力，所有实验均提供设计性实验内容，让学生参与编程。本系统既可作为教师教学的实验演示，又可作为学生动手实验的实验系统。(Signals and Systems Software experimental toolbox, the system includes seven experiments, namely: basic operations signals in time domain, the convolution of continuous signals and continuous-time system time domain analysis, convolution of discrete signals and discrete-time systems when domain analysis, frequency domain signal analysis, continuous signal sampling and recovery, system frequency domain analysis, signal amplitude modulation and demodulation. In order to strengthen the student s computer programming skills and ability to provide all the experiments were designed experiment content, allowing students to participate in programming. This system can be used as experimental demonstration of teaching, but also as a student hands-on experiments the experimental system.)

计算一维和二维卷积,基本可以替代Matlab中的conv和conv2函数,程序很方便就可以移植成C语言..(Calculation of one-dimensional and two-dimensional convolution, the basic alternative to Matlab' s conv and conv2 function, the procedure can be easily transplanted into a C language ..)
