- Abstract
- A single antenna based virtual antenna array at the receiver can be used to find direction of different incoming radio signals impinging at the receiver. In this paper, we investigate the performance of random 3D virtual antenna arrays for DoA estimation. We have computed a Cramer-Rao Lower Bound (CRLB) for DoA estimation if the true antenna positions are not known, but these are estimated with an uncertainty. Position displacement is estimated with an extended Kalman filter (EKF)
by using simulated data samples of acceleration and rotation rate which are corrupted by stochastic errors, such as, white Gaussian
noise and bias drift. Furthermore, the effect of position estimation
error on the DoA estimation... (More) - A single antenna based virtual antenna array at the receiver can be used to find direction of different incoming radio signals impinging at the receiver.
