| Abstract(in English) | Although the spread spectrum achieves stable communication by suppressing interferer by spreading process, since the satellite channel is affected by the Doppler effect, the usable situation is limited. In this paper, we describe the influence of the Doppler effect to acquisition and tracking during orbit transfer to GEO, and the achievable performance of spread spectrum. We propose a receiver design that enables fast signal acquisition over a wideband under strong interferer. This paper provide the result that our receiver design achieves the immunity against 17 dB of interferers with less than 5 seconds of acquisition time. |
