Abstract
The invention claims an apparatus and an associated method for providing transmit diversity to an open-loop MIMO communication scheme such as a point to multipoint broadcast service in a cellular system. Multiple data streams of the broadcast data are broadcast by way of transmit diversity antennas of a sending station. The data symbols of the separate data streams are phase-shifted to be offset in phase from one another. The data streams once the data symbols thereof are selectably phase-shifted by a phase shifter are applied by an applier to sending nodes of the respective cells.
