Abstract
According to one embodiment of the invention, a method of signal modulation includes modulating a signal by providing respective sets of weights to an active array antenna. Each set of weights specifies the same preferential direction for transmission by the active array antenna, but corresponds to a respective different one of a phase and amplitude of the signal in the preferential direction. The respective ones of a phase in the preferential direction provide modulation of the signal.
