Description: 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.

Description: TotalWES.m是主干程序，而DCoef和FCTforAW是里面调用的函数。TotalWES只要实现交错网格有限差分波场数值模拟，其中的FCTforAW是用来消除数值频散的。这些是实现弹性波波场模拟的程序，其它两个文件是实现声波波场模拟的程序-TotalWES.m is the backbone of the procedure, and DCoef and FCTforAW is inside a function call. As long as the realization of TotalWES staggered grid finite difference numerical simulation of wave field, which FCTforAW is used to eliminate the numerical dispersion. These are the realization of elastic wave field simulation procedures, the other two documents are to achieve the sound the ball field simulation procedures

Description: An 8-QAM communications channel simulation in Simulink, constructed from a 16-QAM model and using an I,Q correlation receiver.
QAM (quadrature amplitude modulation) is a method of combining two amplitude-modulated (AM) signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation (PAM) in digital systems, especially in wireless applications. In a QAM signal, there are two carriers, each having the same frequency but differing in phase by 90 degrees (one quarter of a cycle, from which the term quadrature arises). One signal is called the ‘I’ signal, and the other is called the ‘Q’ signal. Mathematically, one of the signals can be represented by a sine wave, and the other by a cosine wave. The two modulated carriers are combined at the source for transmission. At the destination, the carriers are separated, the data is extracted from each, and then the data is combined into the original modulating information. -An 8-QAM communications channel simulation in Simulink, constructed from a 16-QAM model and using an I,Q correlation receiver.
