Abstract
It has been proposed to jointly estimate the angles and delays of the paths in a multipath channel. It is interesting to investigate how this improves the precision of angleofarrival based localization systems. In this paper, we provide measurement results comparing the performance of ESPRITbased algorithms for joint estimation to angle and delayonly estimation in a single and a twopath scenario with different number of antennas and with different maximum length sequences as localization signal. It is shown that in the twopath scenario joint estimation provides improved precision compared to angleonly estimation. This holds true even when reducing the number of antennas used for joint estimation to half the number used for angleonly estimation. Within the results for joint estimation the longer sequences perform best. In the singlepath scenario both methods perform similar to each other. There is no improvement in the precision of delay estimation in the twopath scenario.
