Design of low density parity check codes for modulation and detection

程序对2发2收系统进行SVD算法的仿真。发送信号采用QPSK调制，信道为准静态瑞利平坦衰落信道，引入的噪声为均值为0的高斯白噪声，接收端采用最大似然检测算法，仿真其误比特率特性。(The SVD algorithm simulation program 2 admission system. Send signals using QPSK modulation, channel prevail static Rayleigh flat fading channels, the introduction of noise with mean 0 Gaussian white noise, the receiving end using the maximum likelihood detection algorithm, simulation of the bit error rate characteristics.)

将断层剖面划分为一组网格，并以固定的事件数或固定的扫描半径，计算每个网格点处的b值。然后用色彩表示断层面上b值的分布情况，从而反应断层的应力积累情况，便于地震学家分析该断层是否存在发震的可能(This subroutine creates a grid with spacing dx,dy (in degreees). The size will be selected interactively or grids the entire cross section. The b-value in each volume is computed around a grid point containing ni earthquakes or in between a certain radius. The standard deviation is calcualted either with the max. likelihood or by bootstrapping, when that box is checked. If not, both options can be assigned by the additional run assignment. Standard deviation of b-value in non-bootstrapping case is calculated from Aki-formula!)

本文主要讨论在MATLAB软件中如何实现C程序源代码的移植。结合"道路平整度指数(IRI)预测问题"的实例,将C语言编写自仿射变换分形插值函数,移植(或改写)到MATLAB中,绘制出宁波机场道路平整度的预测图象,为解决预测问题可视化提供帮助。(This paper mainly discusses the MATLAB software, how to achieve C source code of the transplant. Conjunction with the road roughness index (IRI) a projection of the example of C language to self-affine fractal interpolation function transformation, transplantation (or rewritten) to MATLAB, the mapping out of Ningbo airport road roughness prediction image, To address the issue of visual projections to help.)
