本文介绍一种新型多功能对流层散射信道模拟器。它采用贝洛(Bello)短时模型,可以提供两路独立的瑞利衰落信号,衰落率分0.3、1、3c/s三种,最大多径展宽为0.5μs,延迟功率谱可以按需预置,中值电平可以随意改变。两台模拟器可以组合成四重分集模拟器,输出4路具有共延迟功率谱的独立的瑞利衰落信号。模拟中的自动测试装置,可以自动测试记录各种信道参数。该模拟器为世界上为数不多的散射信道模拟器行列增添了功能更完善的一员。 This article describes a new multi-functional troposcatter channel simulator. It uses Bello short-term model, can provide two independent Rayleigh fading signals, the fading rate of 0.3,1,3 c / s three, the maximum multipath broadening of 0.5μs, delay power spectrum can be on demand Set, the median level can be changed. The two simulators can be combined into a quadruple diversity simulator to output four independent Rayleigh fading signals with a coherently delayed power spectrum. Automatic test equipment in the simulation, you can automatically test record various channel parameters. The simulator adds one of the more sophisticated features to one of the few scattering channel simulators in the world.
