Abstract
Through analyzing the disadvantage of traditional automatic identification system( AIS) signal re-connaissance depending heavily on global positioning system( GPS) ,this paper presents an improved algo-rithm which realizes AIS signal detection and bit synchronization according to the correlation result of syn-chronisation sequence in real time, and demodulates AIS signal successively. The improved algorithm doesn′t need to use GPS,resulting in a more simplified design and a lower cost. The package error rate ( PER) is less than 5% at the signal-to-noise ratio of 13 dB.关键词
