In this work some adaptive techniques of an air-interface for a tactical waveform are studied. The techniques are simulated in a mobile scenario with a map-based channel model. The communication system simulator is based on OFDM. The effects of space diversity, both transmit and receive, adaptive modulation and feedback delay have been investigated. Results show that space diversity in combination with adaptive modulation enables a higher system throughput compared to a system with no space diversity. Furthermore, the usage of space diversity reduces the sensitivity to delays of the feedback information.
