Automatic information acquisition of satellite DVB signals
Haolin Gao, Yan Qun Huang, Yiji Fan · 2008
With the widely use of satellite signals and the more data service transported by satellite signals, more information could be attained from these signals. To implement the automatic information acquisition, the fundamental parts, carrier search and data processing are necessary. The carrier search part mainly deal with the acquisition of parameters of carrier such as frequency, bandwidth. The data processing part mainly storage and recovery information such as video and audio signals, MPE signals. The algorithm of carrier frequency search based on waveform characteristic and the method of extracting data from MPE data are discussed in this paper.
