Diversity Combining via Universal Orthogonal Space-Time Transformations. (arXiv:1712.04038v1 [cs.IT])
来源于:arXiv
Receiver diversity methods play a key role in combating the detrimental
effects of fading in wireless communication and other applications. Commonly
used linear diversity methods include maximal ratio combining, equal gain
combining and antenna selection combining. A novel linear combining method is
proposed where a universal orthogonal dimension-reducing space-time
transformation is applied prior to quantization of the signals. The scheme may
be considered as the counterpart of Alamouti modulation, and more generally of
orthogonal space-time block codes. The scheme is well-suited to
reduced-complexity multiple receive-antenna analog-to-digital conversion of
narrowband signals. It also provides a method to achieve diversity-enhanced
relaying of communication signals, for multi-user detection at a remote
terminal, minimizing the required bandwidth used in the links between relays
and terminal. 查看全文>>
