Performance Improvement of Asynchronous UWB Position Location Algorithm Using Multiple Pulse Transmission

The paper provides accuracy improvement of asynchronous UWB position location algorithm using multiple pulse transmission. We eliminate inter symbol interference by increasing time duration between consecutive pulses, and to reduce AWGN noise we transmitted sufficient number of pulses. At the receiver side we averaged signal over time, and performed correlation with template signal. The result shows that the accuracy of asynchronous position location algorithm improved much compare with its initial signal transmission scheme.
