wireless-communication
本论文主要利用MATLAB实现一个简单无线通信系统的仿真,并通过误码率分析系统性能。在文本文件中输入任意字符串(空格或英文字母)作为该通信系
统的信源,经过信源编码、信道编码及信号调制进入信道,信道采用的是瑞利衰落信道,而后对接收到的信号进行解调,完成信道解码、信源解码后,将结果输出到解码文件即信宿中。
(In this thesis, a simple wireless communication system simulation using MATLAB and analyze system performance through the bit error rate. In a text file input any string (spaces or English letters) as the communication system of the letter source, source coding, channel coding and signal modulation into the channel, the channel using the Rayleigh fading channel, the signal is received and then docking demodulates the completion of the channel decoding, source decoding, the result is output to decode the file, i.e. the sink.)

与其它高级语言相比较,MATLAB具有独特的优势:(1) MATLAB是一种跨平台的数学语言。(2) MATLAB是一种超高级语言。MATLAB平台本身是用C语言写成的,所以在编程效率,程序的可读性、可靠性和可移植性上远远超过了常规的高级语言。(3) MATLAB语法简单,编程风格接近数学语言描述,是数学算法开发和验证的最佳工具。(4) MATLAB计算精度很高。与其它语言相比,MATLAB对计算机内存、硬盘空间的要求也是比较高的。(Compared with other high-level languages , MATLAB has unique advantages: (1) MATLAB is a cross-platform language of mathematics. (2) MATLAB is a super-high-level language. MATLAB platform itself is written in C, so the programming efficiency, readability, reliability and portability far more than the regular high-level language. (3) MATLAB syntax is simple, close to the mathematical language to describe the style of programming is a mathematical algorithm development and validation of the best tools. (4) MATLAB computing high accuracy. Compared with other languages , MATLAB computer memory, disk space requirements are relatively high.)

信号瞬时相关函数的傅立叶变换 wvd
Wigner-Ville 分布(简称 WVD)是典型的二次型变换,它定义为信号瞬时相关函数的傅立
叶变换。
由于在计算中不加窗操作,它避免了时域分辨率和频域分辨率之间的相互牵制。
已证明,对于单分量线性调频信号,WVD 的时频表示能量集中性最优。但也正因为不涉
及窗函数,在分析多分量信号时 WVD 会受到交叉项的干扰。(The Wigner-Ville distribution (WVD) is a typical quadratic transformation, which is defined as the Fourier of the instantaneous correlation function of a signal.
Ye Bianhuan.
Because of no window operation in the calculation, it avoids the mutual restraint between time domain resolution and frequency domain resolution.
It has been proved that for the single component LFM signal, the WVD time frequency representation has the best energy concentration. But it is also because it does not involve.
And window functions, when WVD is used to analyze multi-component signals, it will be interfered by cross terms.)
