Bias and variance of asymmetric double-sided two-way ranging
Original language description
The asymmetric double-sided two-way ranging (ADS–TWR) is a method of range estimation through precisely timestamped messages sent between two transceivers. In contrast to the symmetric double-sided two-way ranging (SDS–TWR), the ADS–TWR suppresses the errors induced by transceiver clock drifts even when the message reply delays are unequal. However, due to the nonlinearity of ADS–TWR estimator, its mean and variance cannot be evaluated in neither straightforward nor exact way. This article presents an analytical approach of evaluating an approximation of bias and variance of the range estimators and applies it on an exemplary set of parameters, which is typical for ultra-wide band (UWB) localization systems. Moreover, the obtained results are verified by a Monte–Carlo simulation. It will be proven that the ADS–TWR is safe to be used in most of the present applications and its precision is rather similar to SDS–TWR.
