Method for emulating multipath fading radio channels

摘要

The method involves using a wide-sense stationary uncorrelated scattering or WSSUS model in which the channel pulse response is defined by one equation and the time varying frequency response generated by the Fourier transform of the first equation by a second equation. The pulse response can be viewed as an incoherent superimposition of N echoes, each characterized by a random phase, transition time and Doppler shift. The conventional Monte-Carlo model, in which the parameter set or elements of the parameter set are selected randomly and in a uniform distribution, deterministically or stochastically using uniformly distributed non-linear input variables, is modified with a frequency modulated raster generated by a deterministic or random (stochastic) input raster formed by the non-linear input variables. Independent claims are also included for use of a digital computer to implement the method and use of a hardware simulator to implement the method.
