Wireless communication frame synchronization method and system based on pseudo random sequence

The invention discloses a wireless communication frame synchronization method and system based on a pseudo random sequence. The method comprises the following steps: step A, synchronization frame formation, producing a synchronization frame pulse sequence based on the pseudo random sequence in the transmission; step B, frame synchronization control, periodically performing antenna switching in thereceiving, enabling the onboard upper antenna and lower antenna radio frequency signals to alternatively enter a receiving processing channel; step C, frame synchronization judgment, processing a related peak sequence produced by the receiving processing channel to obtain a captured pulse sequence, and performing the synchronization frame judgment; and step D, reducing a complete synchronizationframe pulse sequence according to the captured pulse sequence to finish the frame synchronization. By adopting the synchronization frame design algorithm, and combining the upper and lower antenna reasonable switching mechanis
