Systems and methods for identifying formality standard

A method, comprising:

• synchronizing a signal using Pseudorandom Noise (PN) sequences, wherein the signal includes a plurality of PN sequences, marked as 0 PN sequence, 1 PN sequence, . . . , (k−1) PN sequence, k PN sequence, wherein k is a positive integer number;
• determining whether the signal is synchronized using the PN sequences;
• in response to that the signal is synchronized, determining a first position corresponding to a first maximum correlation value of the (k−1) PN sequence;
• determining a second position corresponding to a second maximum correlation value of the k PN sequence, wherein the second maximum correlation value of the k PN sequence is within a range, wherein the range is determined based on maximum correlation values of the 0 PN sequence, the 1 PN sequence, . . . , and the (k−1) PN sequence;
• determining a distance between the (k−1) PN sequence and the k PN sequence;
• and
• determining a formality standard of the signal based on the distance between the (k−1) PN sequence and the k PN sequence.

A non-transitory computer readable medium, comprising a set of instructions, wherein when executed by a processor, the set of instructions direct the processor to perform a method, the method comprising:

• synchronizing a signal using Pseudorandom Noise (PN) sequences, wherein the signal includes a plurality of PN sequences, marked as 0 PN sequence, 1 PN sequence, . . . , (k−1) PN sequence, k PN sequence, wherein k is a positive integer number;
• determining whether the signal is synchronized using the PN sequences;
• in response to that the signal is synchronized, determining a first position corresponding to a first maximum correlation value of the (k−1) PN sequence;
