  • Medium access in applications of wireless sensor networks is often uncoordinated while sensor nodes communicate bursty flows of data. Therefore random-access packet-based communication schemes are suitable for such networks. Preamble detection is an important task in packet-based communication protocols. The implementation of a previously proposed preamble detection scheme for low-power, wide-band, asynchronous packet communications is proposed that has built-in characterization features. A digital baseband design for the transmitter part of this scheme was fabricated on IBM Corporation's 130-nm digital CMOS process. Silicon prototypes of the fabricated design were successfully tested. The receiver design of the packet-based communications was prototyped on a Xilinx FPGA. The main goal of this thesis was to first measure the performance of the preamble detector at hardware speed. The second goal was to optimize the detector to reduce its area and power consumption. The optimized preamble detection design was also implemented on a Xilinx FPGA. Test measurements showed that its performance closely follows the non-optimized preamble detection design with half the area and power usage. The presented optimized preamble detection design can be utilized in low-power, high-data-rate applications of wireless sensor networks.
