Ultra Wide-band Baseband Design and Implementation

Mike Shuo-Wei Chen 2002 M.S. (advisor: Robert W. Brodersen).

   One objective of this project is to implement the UWB digital backend. The system is mainly digital, and analog data is sampled with sub-nanosecond spacing. The basic functionality of digital backend is to do signal acquisition and data tracking. Among the many issues, this report will cover from system design to hardware implementation in Module Compiler and FPGA.
    The research target of the baseband design is low power consumption and high flexibility. Low power consumption comes from the low duty-cycle communication mode where one could slow down the pulse transmission rate and relax timing constraint for baseband. Then, we could reduce the supply voltage and push the unused blocks into sleep mode for power saving. The flexibility issue arises from our desire to experiment with UWB, such as changing the data rate or pulse shape, etc. The baseband has to fulfill these missions.
