DTIC ADA152473: Digital Troposcatter Performance Model

The development of a computer prediction model for digital troposcatter communication system design is described. Propagation and modem performance are modeled. These include Path Loss and RSL distributions for troposcatter propagation and mixed troposcatter/diffraction propagation conditions, multipath delay spread and relative delay between the scatter and diffraction component. The modem performance models are for the MD-918 and AN/TRC-170 modems and include the effects of transmitter and receiver filters as well as co-channel and adjacent channel interference. Originator-supplied keywords include: Troposcatter, Diffraction, MD-918 Modem, AN/TRC-170, Propagation Prediction, Multipath Prediction, Error Rate Prediction, and Link Analysis.
