Abstract :
The paper presents performance comparison of different Space-Time Block Codes (STBC) used in wireless Multiple-Input Multiple-Output (MIMO) systems to assure spatial diversity at the transmitter. We compare Alamouti, Tarokh / Jafarkhani / Calderbank and Larsson / Stoica codes. The simulations results confirm that increasing the number of transmit / receive antennas the error rate decreases. Also, for the same number of transmit antennas, codes having zeros in the transmission matrix offer worst performance than those with full matrix.
