COMPARISON OF ALAMOUTI AND DIFFERENTIAL SPACE-TIME CODES FOR AERONAUTICAL TELEMETRY DUAL-ANTENNA TRANSMIT DIVERSITY

International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / 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. Unfortunately, for vehicle attitudes where both antennas have a clear path to the receiving
station, this practice also leads to self-interference nulls, resulting in dramatic degradation
in the average signal integrity. This paper discusses application of unitary space-time codes
such as the Alamouti transmit diversity scheme and unitary differential space-time codes to
overcome the self-interference effect observed in such systems.
