Abstract :
In this paper, for the frequency domain generation of SC-FDMA, i.e., DFT-SOFDMA, with the localized subcarrier mapping, we proposed novel Space-Time Coding and Mapping scheme and Space-Frequency Coding and Mapping scheme, which provides better PAPR property compared with other schemes. The new schemes also provide the capability of low-complexity frequency domain equalization and full space diversity. The low PAPR of the new schemes can be used to improve the power amplifier efficiency and/or enhance the cellular coverage, especially for the uplink of the future broadband wireless communication systems.
