The Lab VIEW Simulation of Space-Time Coding Technique in the MIMO-OFDM System

摘要：

The space-time coding technology in MIMO system and MIMO-OFDM system is analyzed in this paper.The system performance of the Layered Space-Time Codes (LSTCs),the Space-Time Trellis Codes (STTCs) and the Space-Time Block Codes (STBCs) are studied and compared by means of the LabVIEW simulation,which has also compared the bit error rate (BER) in different signal-to-noise ratio (SNK).Several communication systems such as V-BLAST,Trellis and Alamouti coding in different states and different numbers of antennas are simulated by this software.It is proved that the system performance in MIMO system can be effectively improved by means of the space-time coding in BER-SNR graph.We have drawn the conclusion that STTC is the best coding scheme in the three of them.
