Angle-of-Arrival Estimation for UWB Signals Clustered in Angle

In this study, the new signal model suitable for ultrawide band (UWB) environments with random angle spread is proposed to estimate the angle-of-arrivals (AOAs) of clusters in a UWB indoor or indoor-to-outdoor wireless communication. The estimation technique based MUSIC algorithm is investigated and the estimates of the AOA and distribution parameter on the received clusters are obtained. The proposed model and estimation technique are verified using computer simulations, and the performance of the estimation error is analyzed.
