Strong LOS MIMO for Short Range mmWave Communication - Towards 1 Tbps Wireless Data Bus

Abstract

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.

Enabling simultaneous cooling and data transmission in the terahertz band for board-to-board communications

“…Open space wireless solutions, enabled by the appearance of the miniature wireless transceivers working in the mmWaves spectrum, have been recently proposed as an alternative to conventional "wired-in-nature" metallic or fiber connectors [6,7]. These systems are featured with the advantages of wireless communications, including multicasting and broadcasting capabilities, and provide the data rates, sufficient for the intra-computer traffic with relatively low intensity [8].…”

16-QAM OFDM-Based K-Band LoS MIMO Communication System with Alignment Mismatch Compensation

“…Previous works determined that the MIMO technique can be applied in a LoS environment if the transmitting and receiving antennas are properly placed and separated . Various techniques for LoS MIMO communications, such as their applications , , performance improvements , , analyses , and receiver architectures , have also been studied. In , outdoor measurement results indicated that channel phase is affected by abnormal atmospheric variations.…”
