摘要：
The application of LSTBC (Layered Space-Time Block Code) to frequency selective fading channels is presented in this paper. This proposed scheme combines LSTBC and OFDM (Orthogonal Frequency Division Multiplexing). At the receiver, the Group Interference Suppression based on SVD for decoding is adopted. Simulation results show that OFDM-LSTBC outperforms OFDM-BLAST in its ability to combat fading and has a higher spectrum efficiency and a higher code rate than OFDM-STBC.
