SATELLITE COMMUNICATION TRANSMITTER AND RECEIVER FOR MITIGATING CHANNEL INTERFERENCE |
摘要 |
PURPOSE: A satellite communication transceiver for mitigating interference is provided to improve performance in mobile body Doppler environment and non-linear amplification module by applying a band spreading technology based on direct sequence to a DVB-S2(Digital Video Broadcasting-via Satellite second generation) system. CONSTITUTION: A modulator(100) modulates a satellite communication signal. A band spreading unit(110) transmits the signal to outside after band spreading. The band spreading unit includes a matching filter unit(120), a decimation unit(130) and a direct sequence band spreading unit(140). The direct sequence band spreading unit includes a band spreading code applier(150), a scrambling unit(160), a oversampling unit(170) and a pulse forming unit(180).
