Abstract:

The UWB communication technology has many features that differentiate it from the conventional communication technologies, including low power spectra l density, strong security, strong penetrating power, multipath anti-jamming, and so on, which is especially suitable for the high-speed wireless access  in dense multi-path environments and military communications. The paper gives a design approach to 100Mbps UWB testing   he TH-PPM modulation,and introduces the organization of the system, the principle of working and the scheme of implementation. Meanwhile, the paper deta iledly discusses the pivotal portion of the system, which includes the synchronization and acquisition, convolution,and interleaving. Finally, the paper  validates the feasibility of the design via an experimental test on the UWB platform in an indoor way.

Key words: UWB, synchronization and acquisition, convolution, interleaving
