Abstract
Combining with UWB location technology, TOA location algorithm is presented. The first step is statistically averaging the received signals to mitigate impact of AWGN as long as possible. Using incoherent power detection algorithm obtain rude TOA estimation which is made incoherent power detection once more in the second step so as to further optimize in time. The simulation results show that the algorithm under low computational complexity can effectively improve ranging performance and location precision.
