After the phasing signal synchronization, information began to receive;
If error rate of received was more than 33%, will refuse to received the information.
Information storage and the same text information rejected:
If the information received packet error rate is less than 33%, the information will be saved, after the same text message will be rejected;
For example, two received error rate for the same information in a 4% -33%, save for the lower one.
Storage of information and the identification number (ID):
Information identifier (ID) can be stored up to 600;
