Abstract
Methods and apparatus of allocating antennas for cyclic delay diversity (CDD) transmission are disclosed. One method includes estimating a transmission channel of a transceiver having a plurality of antennas. A subset of a plurality of transceiver antennas is selected based on the estimated transmission channel. A single transceiver antenna of the subset is identified based on a channel quality of a transmission path of the single transceiver antenna. Cyclic delay diversity (CDD) signals are transmitted from the subset of the plurality of antennas, wherein a minimally delayed CDD signal is transmitted from the identified single transceiver antenna of the subset of the plurality of transceiver antennas.
