In this paper eigen-beamforming and differential space-time modulation (DSTM) are combined together to construct a robust and relatively simple system for multiple-input multiple-output (MIMO) Ricean fading channels. A transmission scheme with feedback link is developed here that combines beamforming with differential multi-antenna modulation based on orthogonal space-time block coding. The power...
A digital beamforming differential space-time block modulator (DBF-DSTM) scheme used in air-ground communication is proposed in this paper. By using DBF other interferences caused by other airplanes can be cancelled because of different directions of arrival (DOAs). Corresponding adaptive beamforming algorithm is also proposed for this system to decrease the influence of other airplanes' interferences...
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...
A novel multiple antenna DAB/DMB scheme based on differential unitary space-frequency modulation (DUSFM) is proposed in this paper, in which the receiver can demodulate without channel status information in a maximum-likelihood method. We proved theoretically that in case an ideal interleaving, the DUSFM-DAB system can obtain full space-time- frequency diversity, up to the product of the convolutional...
