Cluster Angle-of-Arrival Estimation for UWB Indoor System
IEICE Transactions on Communications, 2005In this study, the new signal model suitable for ultrawide band (UWB) indoor environments with random angle spread is proposed to estimate the angle-of-arrivals (AOAs) of clusters in a UWB wireless communication. The subspace based estimation technique adopted for this model is investigated and the estimates of the AOA and distribution parameter on the

Estimating angles of arrivals in the presence of mutual coupling
1987 Antennas and Propagation Society International Symposium, 2005In this paper, we examine the eigenstructure of the covariance matrix of an antenna array under mutual coupling and show that its distortion can be properly compensated by using a modified search vector in performing estimations. Computer simulation results are presented. They validate our analysis. FORMULATION Let us consider the problem of estimating

Angle of Arrival Estimation for Non-Circular Signals
2006 IEEE Sarnoff Symposium, 2006A new algorithm is introduced in this paper that estimates one dimension direction of arrivals utilizing coherent and noncoherent non-circular sources. Examples of such sources are binary shift keying (BPSK) and M-ary amplitude shift keying (MASK). This algorithm presents several advantages over the classical subspace algorithms such as Root MUSIC and ...

Angle of Arrival Estimation for Saturated Acoustic Signals
2013Abstract : The U.S. Army Research Laboratory (ARL) has developed a tetrahedral microphone array system for acoustic-based target detection and localization. Time-domain data can be used to obtain differential time of arrival (DTOA) and angle of arrival (AOA) estimates. Use of multiple arrays allows for triangulation.
