In this paper, we investigate the performance of different blind adaptive array algorithms in aeronautical communication systems. A novel algorithm named least-squares spread despread constant modulus algorithm (LS-SDCMA) is developed. The performance of the novel algorithm is compared with that of the existing multitarget least-squares constant modulus algorithm (MT-LSCMA) in the practical case and...
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...
