Abstract
A communication device, method, and computer program product optimize cyclic delay diversity (CDD) or linear delay diversity (LDD) for effective transmit diversity that increases transmit power by first and second transmit chains of the communication device. A controller of the communication device sequentially configures the first transmit chain to transmit an uplink signal and the second transmit chain to transmit the uplink signal with a different phase shift or time delay value. While sequentially transmitting, the controller monitors a measure of uplink signal quality at a network node for each sequentially changed phase shift or time delay values. The controller determines and uses an optimum value for the phase shift or time delay value that results in an optimum uplink signal quality over the evaluated sequence of different phase shift or time delay values.
