Identification of a radio channel to an antenna array, using a parametrization in direction of arrival and gains of signal paths, has been investigated. This channel estimate is compared to a least squares FIR channel identification. For the scenarios studied, the parametrized method had better performance than the least squares method. The parametrized method is however more complex and relies on estimates of the number of signals arriving to the antenna array.
