Patent ID: 8693524

Claim:
An impulse system ultra-wideband (UWB) synchronization method, characterized in that: the method uses frames as the basic unit in data transmission; each frame is divided into a preamble symbol part and a data part, wherein the preamble symbol part transmits known pulse sequence which is used for channel estimation and synchronization, while the data part carries the information to be transmitted; the preamble symbol part further comprises two parts of positive and negative pulse sequence and co-current pulse sequence; the front part of which is the positive and negative pulse sequence and contains odd number of impulses with alternant positive and negative polarities, while the rear part of which is the co-current pulse sequence and consists of impulses of same polarity; and the impulse polarity in the co-current pulse sequence is same as the impulse polarity of a last impulse in the positive and negative pulse sequence.
