ABSTRACT:
Where there is a difference in the angle of arrival between desired incom signals and interfering signals, the reception of the desired signals is maximized by the creation of nulls in the direction of the interfering signals. A high quality receiving (or transmitting) beam is formed by a one-time calculation of the proper phase or amplitude adjustment required to create a null in the direction of each interfering signal. The antennae are then appropriately adjusted to establish the nulls.
