摘要
探讨了数字卫星电视接收的几项关键技术 ,指出留足门限余量 ;减少相位噪声 ;实现极化匹配 ;选择本振频率准确度和稳定度高的高频头 (LNB) ;
A few of critical techniques about satellite digital-TV receiving are discussed,which include leaving enough threshold voltage value,reducing phase noise,realizing polarization match,selecting LNB of high steady local oscillator,and avoiding disturbing from the same frequency.They are the prvocal techniques that assure receiving excellent digital satellite TV signal.
