Rain Attenuation and Doppler Shift Compensation for Satellite Communications

Abstract: structure and the ability to effectively compensate for rain attenuation and the Doppler shift.The non-geostationary satellite channel for high speed communications cannot be considered an additive white Gaussian noise (AWGN) channel because of signal fading due to rain and the Doppler shift on the channel. For these reasons, we developed our own rain attenuation model with which we can synthesize the dynamic characteristics of rain attenuation. Carrier offset induced by the Doppler shift is also modeled by th… Show more

“…Ka-band link is vulnerable to rain attenuation, and thus we also generated dynamic rain attenuation [16], so that the transmitted data would experience dynamic behaviours of rain attenuation, shadowing and small-scale fading. We generate rain attenuation samples with an interval of about a second.…”

“…S c i is the spectrum efficiency of the channel code C i and calculated by the value of 1 À P c i ðgÞ; where P c i ðgÞ is the bit error rate (BER) for the predicted SNR, g. The weighting factor, l, is inversely proportional to the slope of the SNR, Dg. When the slope of the SNR slop increases, it means that the channel changes rapidly, in which case a smaller l decreases the effect of previous CQI [16]. For multimedia transmission, we consider a target BER of 10 À5 which may correspond to the requirement of real time streaming services using MPEG-4 audio/video transmission.…”

“…DDBHP relies on estimating Doppler shift for each MS onboard the satellite to accomplish this task. The latter procedure is part of compensation techniques used for establishing communication between satellite and MS [9], [10] and therefore does not add any complexity. The advantage of measuring Doppler shift onboard the satellite is that location information regarding MSs is produced where is needed, thus avoiding the cost involved in its distribution.…”
