对现有的移动的无线电天线衰落信号模型进行了推广。一般化在于让散射波不一定水平传播。这种推广的影响进行了调查有关的概率密度函数（PDF），相关性能，功率谱的相位和包络。pdf不受影响，但包络的功率谱受到显著影响。这个广义谱比原来的更光滑，而且总是有限的，而后者不是。因此，它被认为是广义模型与测量光谱，特别是在城市环境中更一致。
A generalization of an existing model for the fading signal at a mobile radio antenna has been made. The generalization lies in letting the scattering waves not necessarily be traveling horizontally. The effects of this generalization are investigated concerning probability density function (pdf), correlational properties, and power spectra of the phase and envelope. The pdf is not affected, but the power spectrum of the envelope is significantly affected. This generalized spectrum is smoother than the original and always finite, which the latter is not. Thus it is assumed that the generalized model is more consistent with measured spectra, especially in urban environments.
