Antenna Array Design for LOS-MIMO and Gigabit Ethernet Switch-Based Gbps Radio System
The high spectrum efficiency of multiple-input multiple-output (MIMO) transmission traditionally depends on the high multiplexing gain in rich scattering environments, which will not always hold in the line-of-sight (LOS) environments, especially at higher microwave frequency band. In this paper, a...

The high spectrum efficiency of multiple-input multiple-output (MIMO) transmission traditionally
depends on the high multiplexing gain in rich scattering environments, which will
not always hold in the line-of-sight (LOS) environments, especially at higher microwave frequency
band. In this paper, a novel antenna array design rule is proposed to guarantee full
multiplexing gain for LOS-MIMO systems with one- or two-dimensional antenna arrays in
LOS scenarios, and the strict perpendicular constraint is released in the two-dimensional case.
The minimum antenna array area and the performance sensitivity to the area error are also
obtained to guide the practical system design. Then, a demo MIMO-OFDM system with the
designed square antenna array at 15 GHz carrier is implemented on a novel Gigabit Ethernet
(GE) switch-based software defined radio (SDR) platform, which combines the hardware
accelerating units (HAUs) with the general-purpose processors (GPPs). The field evaluation
results show that the system throughput and spectrum efficiency are greater than 1 Gbps and
15 bps/Hz, respectively. To the best of our knowledge, it is the first time to demonstrate
the Gbps LOS-MIMO-OFDM system at such microwave bands in the world, which can be a
successful design example for the next generation wireless backhaul or fixed wireless access. |
