Abstract：Ka-band satellite communication system, therefore, for all its advantages, such as an offer of a large bandwidth,a huge capacity of communications,a narrow wave beam, a reasonably small terminal size a possible capacity for more satellites on the orbit plane and excellent anti-interference performance,will be an inexorable trend in the future satellite communication.However,the influence of rain attenuation in Ka-band satallite communication system is extremely serious.In this paper,the adaptive coding and modulation technology based on Q-ary LDPC codes is put forward to reduce rain attention.
