COMPLEX ENVELOPE 3-STATE MARKOV MODEL-BASED SIMULATOR FOR THE NARROW-BAND LMS CHANNEL

S-band measured land mobile satellite (LMS) propagation data were proc essed in order to obtain the parameters of a three-state Markov chain model for several environmental and elevation angle conditions. In thi s paper the results of this study are reported. The model was extended to produce a narrow-band complex envelope simulator. This simulator p roduces as an output a complex time series representing the received s ignal complex envelope variations. This approach allows relevant param eters of the channel such as phase variations, random FM, Doppler shif t spectra, etc. to be present in the simulated time series.
