7.2 Alamouti Scheme for MIMO System
The Alamouti technique is a transmit diversity shames which can be used with MIMO
wireless system of two transmitter and four receiver to offer a diversity gain of 2 ×
2. As p is the time slots which is used to transmit j symbols, the bite rate R given by
R = j/p. For example, the rate of 2 × 2 MIMO configuration is one. The Alamouti
scheme works independently of the number of receive ports.
The Alamouti code 0 is the most known ST coding scheme with full diversity and
code rate one. The received signal can be written as follows:
