Abstract. A numerical model of a forward link for the Express-RV satellite system in highly elliptical orbit has been developed for simulating broadband data transmission. The channel model encompasses signal propagation along the uplink, transponder processing, downlink propagation, and impairments within the user terminal. An analytical description of the distortions introduced at each stage of the radio channel model is presented. The model has been implemented in MatLab. The modeling results allow us to estimate the influence of radio channel factors on communication quality and formulate requirements for digital signal processing algorithms, according to which modem equipment is designed. Calculation of the link budget allows us to specify the payload parameters.
Key words: numerical model of radio channel, satellite communication system, Express-RV, highly elliptical orbit, satellite transponder, propagation in the subscriber's local environment, uplink, downlink, subscriber terminal, satellite communication center.
