Abstract :
The authors introduce a wave frame model and define the covariance of vector angular frame model (CVAE) in this frame. A lower bound is derived on the CVAE for source direction and orientation estimation. An explicit expression for the CVAE matrix bound is found to be diagonal, easy to interpret, and having only intrinsic singularities. A relationship is also provided between the CVAE and the mean-square angular error quality measure
