采用k空间方法仿真超声声场及光声、剪切波传播等的专用matlab工具箱程序包，能模拟非均匀介质情况下的波动传播情况，功能强大，-k-wave toolbox for ultrasound simulation . (K-space method using ultrasonic sound field simulation and photoacoustic, shear wave propagation matlab toolbox, such as special packages that can simulate wave propagation in inhomogeneous media situation in case, powerful,-k-wave toolbox for ultrasound simulation.)

说明：  对CDMA系统中进行多用户检测算法的仿真分析(CDMA system for multi-user detection algorithm for the simulation analysis)

本程序可以对一个模拟信号进行数字化，使用的是PCM即脉冲编码调制，其结果是将样值转化为8位PCM编码。现今语音编码大多数采用这类编码方法(This procedure can be an analog signal to digital, using pulse code modulation or PCM, and the result is kind of value will be translated into eight PCM coding. Most of the current speech coding to adopt this type of coding method)

The optimal quantization tables for Gaussian, Rayleigh and Laplacian probability density functions.Uniform quantizer is optimal for uniform distribution source, not for other distribution.The procedure is based on a Lloyd-Max iteration.

compensation of dead time effect of the inverter dead time effect causes the impact of the control performance of the INVERTER system, and pointed out that the dead time compensation, the key lies in the current phase of the acquisition, in order to overcome the practical zero of the current ambiguity of the system is proposed based on the two-phase stationary coordinate system under the feedforward dead-time compensation method. by the offset voltage of the three-phase output current cycle Fourier transform is found only compensation 1, 5, 7 harmonic components to eliminate the dead time effect. simulation and experimental results verify the correctness and feasibility of this approach.
