Abstract

Realistic models and processes for simulation of wireless information transport systems are provided which replicate all time and frequency dynamics effects on stationary and mobile communications systems. The preferred embodiment is a realsitic modeling apparatus for simulation of wireless information transport systems comprising a data entry module, a communications traffic selection module, a driver database, and voice and data input modules furnishing a simulation input to a network simulation module. The network simulation module having communications realism effects, a DIS structure, a channel error-burst model to transmit random errors, and a multipath modeling module to integrate deterministic and stochastic effects. The multipath modeling module, having a digital radio model and a Terrain-Integrated Rough Earth Model, influences the simulation inputs forming a multipath output, which is adjusted by voice and data inputs to provide a realistic, real-time simulation output signal to a display module portraying the simulated communications network and link connectivity. The network simulation module, channel error-burst model and multipath modeling module comprise a number of computer programs. A method for realistic simulation of wireless information transport systems in real-time utilizing modeling techniques and computer programs is also disclosed.
