Space-Time Turbo code is an effective method for the enhancement of link capacity and maximizing the link-budget by balancing the coding gain obtained via Turbo codes and the diversity gain obtained through multiple antenna transmission A study on an antenna selection scheme for Space-Time Turbo code for OFDM systems is presented in this paper In the proposed method, the systematic bits and the punctured parity bits are sent from the selected antenna for each sub-carrier, while data transmission is suspended from the antenna experiencing poor channel conditions at the receiver Simulation results show that the proposed method yields a 22dB gain in the required TxE_b/N_0 relative to the conventional method, and makes the channel estimation accuracy more robust Moreover, the proposed method reduces transmission power by about 4dB compared to the conventional method
