In this letter, we consider a distributed satellite MIMO scenario that includes two GEO satellites and a uniform linear array (ULA). The effect of geometrical arrangement of ULA on channel capacity is investigated, and it is proved that the optimal c

As a typical technique of the fourth and fifth generation mobile communication, Multiple-Input and Multiple-Output (MIMO) technology can achieve the optimal channel capacity by configuring the antenna azimuth, which can improve the performance of the

Through a common set of analogue coefficients and a simple digital coding scheme in the form of ones and minus ones, a previous technique can only multiplex two beams whose directions satisfy a fixed relationship. In this work, two novel designs are

A practical massive multi-input multi-output (mMIMO) relay, due to limited antenna spacing and the use of cost-effective equipment, usually experiences spatially correlated channels and hardware impairments, respectively. We consider a hardware-impai

Spatial correlation is a crucial impairment for practical Multiple Input Multiple Output (MIMO) wireless communication systems. It is important to consider spatial correlation between antennas in actual communication scenario at both sides, i.e. tran

In practical large-scale optical phased array (OPA) design, large antenna spacing is required to accommodate the device size and the routing area. Therefore, under the traditional uniform antenna arrangement, grating lobes result in very limited fiel
