Alamouti Coding is a spatial-time block code (STBC) which exploits the spatial diversity at the transmitter for a two-transmitter system. It was proposed by Siavash M. Alamouti back in 1998.

The output out of the transmitter is given by the following equation:


where columns represent the transmit antenna and the rows represent time. and are two consecutive symbol inputs into the Alamouti encoder.
