A Study of Realization of AIS Communication Protocols with DSP
Jiachun Zheng · Navigation of China · 2005
According to the communication protocols of AIS( Automatic Identification System), the ways to implement the communication protocols by using high performance DSP(digital signal processor) are studied. The following are introduce in detail: the composition of the system, the software realization of the HDLC protocol which includes the checking of CRC code, packing and unpacking, the data transfer, the slots distribution and management, UTC timing etc. The results of debugging the system show that these approaches are feasible.
