This code was used for making the practical measurements in section 2.3 of my thesis. This Matlab code allows an OFDM signal to be generated based on an input data file. The data can be random data, a grey scale image, a wave file, or any type of file. The generated OFDM signal is stored as a windows wave file, allowing it to be viewed, listened to and manipulated in other programs. The modified wave file can then be decoded by the receiver software to extract the original data. This code was developed for the experiments that I performed in my honours thesis, and thus has not been fully debugged. This is the original code developed for the thesis and so has several problems with it. The BER performance given by the simulations is infact Symbol Error Rate.

利用Matlab 的Simulink工具箱设计一个控制系统框图，本设计的主要内容是双闭环直流电机调速系统的动态结构框图，本设计基于大学本科“电机拖动与运动控制”课程中双闭环直流电机调速系统的模型设计，建模仿真结果与教材理论分析结果相同。(Use of Matlab Simulink toolbox to design a control system block diagram of this design is the dynamic structure of the dual closed loop DC motor speed control system block diagram, the design is based on the curriculum of undergraduate motor drive and exercise control "dual closed loop DC machine tunespeed system model design, modeling and simulation results and textbook theory analysis results are the same.)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)

Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory, associative storage, or associative array, although the last term is more often used for a programming data structure.

CRC校验，实现基本的CRC校验功能，当mask不同时，修改也相当方便(CRC checksum, CRC checksum to achieve the basic function, when the mask is not the same time, changes are also very convenient)
