Abstract :
The placement of two antennas on an air vehicle is one possible practice for overcoming signal obstruction created by vehicle maneuvering during air-to-ground transmission. However, for some vehicle attitudes, this practice also leads to self-interference s. This paper discusses application of unitary space-time codes such as the Alamouti and differential transmit diversity schemes to overcome the self-interference effect observed in such systems.
