adaptive communications
7.The technology of digital beamforming (DBF) can dramatically increase array antenna performances. These performances include fast adaptive pattern nulling, ultra-low sidelobes, closely spaced multiple beams, adaptive space-time processing, high resolution direction fiding(DF) and increased capacity for band-limited communications systems.
8.In this paper, a self - adaptive full - duplex selective ARQ protocol and its corresponding algorithm were presented for the wireless long distance point - to - point communications.
9.Based on adaptive transmission, in this paper, several key technologies are studied on the wide-band wireless digital communications. The basic idea is to decrease system spending, optimize the whole system performance, reduce computation complexity, shorten transmission delay, improve the real-time processing capability, and cut cost.
10.Thereceiver with AAA (adaptive Array Antenna) can differentiate signals from each otherby their different spatial signature. Besides, the receiver can get diversity gain frommore than one element, so as to be helpful to improve the quality of communications.
