ABSTRACT:
Embodiments of the present invention include a method and apparatus for modifying a transmit diversity signal by control of at least a relative parameter, for example, phase difference, in a first signal relative to at least one second signal using various switching modules or techniques. In some embodiments of the invention, the relative difference may be controlled by switching paths, or producing various degrees of relative difference by switching, activating or controlling multiple elements with various resolutions of the relative parameter, or by connecting elements by timing of switches.
