The energy detection (ED) receiver is a practical solution for time of arrival (TOA) estimation in ultra wideband (UWB) ranging. The task of TOA estimation under UWB dense multipath channel is to determine the direct path (DP). In the ED receiver, threshold-crossing (TC) is used a lot. However, the threshold should be elaborately chosen, or else the false detection probability will be high. It is...
To improve time based impulse radio ultra wideband (IR UWB) ranging with energy detection (ED) receiver and make it easy to operate, we consider the power transformation in the study. TOA estimation accuracy depends on the detection of the first path (FP). However, the FP is hard to detect under low signal to noise ratios (SNR). Theoretically, the output of the receiver follows the central or non-central...
