Abstract
In this paper, we evaluate performance of IR-UWB positioning system, which is based on the angle-of-arrival (AOA) and time-of-arrival (TOA) estimation techniques, with different IR-UWB waveforms, such as root raised cosine pulse, 5th order Gaussian mono-pulse, 4th modified Hermite pulse (MHP), and sine-type prolate shperoidal pulse. For ranging performance evaluation, the minimum mean square error (MMSE) technique is employed to resolve the multipath components, and the ranging performance is evaluated with various waveforms. For high precision angle estimation, the multiple signal identification and classification (MUSIC) method is employed. Simulation results show that the MHP pulse outperforms other considered waveforms in a hybrid TOA/AOA based IR-UWB positioning system.KeywordsTOAAOAIR-UWBMMSEMUSIC
