Abstract :
In this paper beamforming and differential space-time modulation (DSTM) are combined together to construct a robust system for multiple-input multiple-output (MIMO) aeronautical channels. A transmission scheme is developed here that combines digital beamforming (DBF) with differential multi-antenna modulation based on orthogonal space-time block coding (STBC). The minimum variance distortionless response (MVDR) algorithm is modified to make it suitable for multiple transmit antenna system. The simulation results proved that the transmitting scheme is an effective way to solve the problem with performance, complexity, and transmission rate for aeronautical communications.
