Orthogonal Frequency Division Multiple Access (OFDMA) is a technology for higher date rates in next generation of wireless communication standards. Efficient diversity in frequency selective channels improves data rates in LTE. LTE is a part of 3GPP and it evolved from the UMTS technology. User channelization is used to enhance the diversity techniques in time varying channels. Existing schemes provide efficient diversity based on subcarrier locations. They capture diversities technique based on resource structure. The existing methods are implemented for one type of diversity and not considering the time variations in the transmission frame.
