Abstract
An acquisition algorithm for a transmitted reference (TR) ultra wideband (UWB) receiver is developed that uses the statistical properties of TR-UWB signals to distinguish between noise and data, achieve acquisition and ignores or decodes the incoming samples accordingly. Unknown parameters, like noise power and arriving time, are estimated and continuously updated once new data is acquired, enabling the receiver to adapt to changing environments. The acquisition is a detection problem with unknown arriving time and noise power. It is split into two steps, chip level and symbol level acquisition. Only segments that pass the first step are considered for the second step. This approach reduces the computational complexity and the implementationspsila resource demands.
