摘要：

Clustered DFT-S-OFDM has been accepted as the uplink multiple access scheme for LTE-Advanced. In this paper, a new transmit diversity with four transmit antennas is proposed for Clustered DFT-S-OFDM system. A modified Frequency Switched Transmit Diversity (FSTD) algorithm is proposed, where the multiple clusters can be divided into two groups by four antennas, thus the number of clusters on each antenna will be reduced. As a result, the PAPR performance of each antenna has been improved. Meanwhile, in order to obtain additional frequency diversity gain, the proposed scheme has introduced more channels by a symbol-based dynamic cluster allocation method, which makes one turbo coded stream transmitted multiple channels. Moreover, the Space-Time Block Coding (STBC) is employed for the two antennas in each group to achieve spatial diversity and coding gain. Simulation results show that the proposed scheme has good PAPR and Bit Block Error Rate (BLER) performance on frequency selective MIMO channels.
