“…Next, for analysis, we set the node separation at receiver and transmitter as d R = 10, 25, and 55 m and d T = 1 m, respectively. For both IA and non IA, it can be seen that as d R is varied from 10 m to 25 m, the performance improves and this trend continues even at d R = 55 m. Hence, our result is in line with [10,21], that node separation at the receiver or transmitter provides independent channel further exploiting spatial multiplexing and diversity. It is clear that there is a drastic degradation in BER performance in IA in comparison with non IA case.…”

“…It is required to choose b 21 and b 11 as two independent vectors and, therefore, b 22 and b 12 are obtained from (16) and (17). For illustrating the communication along a rank 1 channel, we first consider the case of receiver 1.…”

We propose and analyze eigenbeam transmission over lineof-sight (LOS) multiple-input multiple-output (MIMO) channels with linear reception. In particular, we consider fixed point-to-point microwave links for which the singular value decomposition of the LOS MIMO channel matrix is analytically derived. We demonstrate that the Tx eigenbeams can be defined without channel state information at the transmitter and that the beams admit an insightful physical interpretation. We also evaluate the performance of a lattice-reduction aided linear receiver through numerical simulations.

“…Some previous works have come down to antenna array design for LOS-MIMO. Reference [8] analyzed the optimal condition for uniform linear array (ULA), and a 40-GHz LOS-MIMO system is presented in [9] using ULA. The antenna arrays are extended to square and rectangle in [10,11], but the two axes for the array should be perpendicular.…”

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.
