  • Patent number: 8693524
    Abstract: A synchronization method for impulse system ultra-wideband takes frame as basic unit for data transmission, each frame is divided into a preamble symbol part and a data part, wherein the preamble symbol part sends a known impulse sequence for channel estimation and synchronization; the data part takes the information to be transmitted; the preamble symbol part is divided into two parts of a positive and negative impulse sequence, which includes odd impulses with alternant positive and negative polarities, and a same direction impulse sequence, which is composed of impulses with same polarity and is the same as the polarity of the last impulse in the positive and negative impulse sequence. The method provides such advantages as high synchronization precision, small storage space, and capability of immediately finding out the synchronization position etc., and provides an important value for the development of the impulse system ultra-wideband wireless communication technique.

  • Patent number: 8472499
    Abstract: An adaptive multi-channel architecture for a wireless network is provided. A frequency hopping sequence generator module is compliant with a frequency hopping spread spectrum (FHSS) communications protocol. The frequency hopping sequence generator module is capable of performing FHSS concurrently on a plurality of communications channels. A frequency replacement module is coupled to the frequency hopping sequence generator module. The frequency replacement module is configured to receive feedback data over a feedback channel and adaptively select a transmission channel from the plurality of communications channels using the feedback data.
