This program is designed to find the parameters of the method of least squares, building eksperimetalnyh and theoretical curves for to assess the quality of approximation for propagation occurs trend of all their characteristics: propagation time,

瑞利衰落信道，是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。这一信道模型能够描述由电离层和对流层反射的短波信道，以及建筑物密集的城市环境。-Rayleigh fading channels, the statistical model of a radio signal propagation environment. This model assumes that after the signal through

WLAN设备的传播损耗计算模型，主要是指以下：Devasirvatham模型，也称为线性路径衰减模型，可用于各种建筑材料2.4G电磁穿透损耗的经验衰减因子模型信号的穿透损耗在这个阶段。-Both WLAN propagation loss calculation model is mainly refer to the following: Devasirvatham model, also known as a linear path attenuation model, the attenu
