“…However, post processing can be applied for parallelization or equalization of the transmitted signals. Works in [10], [11] have shown that analog components like delay lines or phase shifters are capable to create an analog equalizing network that mixes received copies from different antennas and reconstructs the transmitted signals correspondingly. Due to the fact that the sub-channels are deterministic channels, the equalizing networks aiming at creating independent parallel channels have not to be adaptive.…”

In this paper, we propose a wireless data bus system design which relies on a strong Line-of-Sight MIMO approach. An analog MIMO equalizer, which equalizes the deterministic MIMO channel is involved. Instead of interference suppression, the analog MIMO equalizer aligns the phases of the received signals and enhances the desired signal while it suppresses the undesired ones simultaneously. Although the magnitudes of different signal components of the received signals are preferred to be unique, further studies are applied in our work to investigate the validation of our system design with non-unique magnitudes by using practical on-board antennas. It is shown that the proposed system works well with non-unique magnitudes where undesired remaining interference occurs with limited power in comparison with the desired ones. Furthermore, the proposed design shows a great potential for putting a 1 Tbps wireless data bus into practical systems with moderate transmit power and fairly simple modulation schemes which provide high energy efficiency.

“…However, when transmit and receive antennas are suitably spaced, it has become known that the MIMO technique can be applied in a LoS environment [3]. Furthermore, theoretical studies have provided the opportunity to analyze the LoS MIMO performance [4], [5] and 10 GHz/60 GHz band H/W prototypes probe the possibility of this technique [6], [7]. However, studies on the variations in signal-to-interference ratio (SIR) by antenna spacing and an amplitude mismatch are very rare.…”

“…The main advantage of using MIMO at mm-wave bands is that by having a proper inter-element spacing in both transmitting and receiving antennas, multiple independent streams, and thus high capacity, can be obtained, even in LOS [5]. Different LOS MIMO systems have been proposed and tested indoor [6] and outdoor [7,8]. Another unique characteristic of mmwave band communications is that highly directional beams can be obtained using relatively small antennas.…”

In this paper we evaluate the feasibility of short range outdoor mm-wave MIMO links in the 70 GHz portion of the E-band (71-76 GHz). We use phased arrays in order to strongly reduce the impact of the multipath components, thus making the channel mainly line-of-sight (LOS). We design the array using a simple patch as a single element and simulate the performances for a 200 m link and a MIMO system with equal element spacing at the transmitter and the receiver. Each node of the MIMO system consists of a uniform rectangular array (URA) where the single element is a patch antenna, in order to achieve higher gains and narrow beams. Such configuration is much more compact compared to the antennas currently employed for the same bandwidth. We optimize the interelement distances at the transmitter and the receiver and evaluate the capacity achievable with different array sizes. The results show that, for the proposed link budget, capacity up to 29 bit/s/Hz is achievable at a range of 200 m, with practical dimensions. We also show that the beamforming capabilities make the design much more flexible than the single reflector antenna systems. In the last part of the paper, we verify that our antenna can also operate in rainy conditions and longer ranges.
