This file is the programs of (chapter 2) of book (Modeling the Wireless Propagation Channel a Simulation Approach with MATLAB) which is related to shadowing effects. It helps you to simulate wireless shadowing effects.

根轨迹分析法以图的方式来形象说明系统的零极点及稳定性。(Root locus analysis to figure a way to explain the system s image of pole-zero and stability.)

可以实现ofdm的LS信道估计，并与未采用估计时进行比较(The LS can ofdm channel estimation, and with no comparison with estimates)

说明：  matlab程序解非线性方程KVD方程，非常方便(matlab)

线阵，面阵，圆阵方向图，包含极坐标图，和三维图(Linear array, planar array, circular array pattern, including Polar, and three-dimensional map)

comfac算法是三线性模型常见的数据检测方法。它首先将三线性数据通过tucker3模型压缩，然后通过最小二乘的方法不断更新数据，直到收敛，得到估计值( The algorithm works by first compressing the data using a Tucker3 models. Subsequently the PARAFAC model is fitted to the compressed array, either initialized with DTLD (~ESPRIT) or with PARAFAC-ALS. The solution is de-compressed to the original space, and a few safe-guard PARAFAC-ALS steps are performed. Further optimization of this algorithm is possible, e.g. if the data are very large, if the profiles are very correlated or if the noise is huge. This 、 has not been pursued here, in order to have a generally applicable algorithm)

信号在多径衰落信道中传输特性的研究 当信号在无线信道传播时，多径发射和衰减的变化将使信号经历随机波动。因此，无线信道的特性是不确定的，随机变化的。(Signal in multipath fading channel transmission characteristics)
