TRANSPOSED STRUCTURE FOR CYCLIC DELAY DIVERSITY (CDD) BASED PRECODING

摘要

Systems and methodologies are described that facilitate applying cyclic d elay diversity (CDD) and precoding to wireless transmissions. In particular, data vectors to be transmitted to a number of receive antennas of a receive r can be transformed to a virtual antenna domain. CDD can be applied to this domain followed by precoding to allow the benefits of precoding to remain t hough CDD is applied. In this regard, the resulting signals can be transmitt ed without pouring transmission energy into null spaces unreachable by recei ving devices.
