Abstract
This paper investigates the uplink transmissions from a target user to a holographic MIMO surface (HMIMOS) receiver in the presence of multiple interfering users under the line-of-sight (LOS) channels. The HMIMOS-receiver has a rectangular continuous-aperture HMIMOS and a single RF chain. Approximations of the equivalent signal channel and interference channels are derived in closed-forms. Then the system signal-to-interference-plus-noise ratio (SINR) is obtained. Through rigorous asymptotic analysis we are able to identify the major contributors of the interference, and propose a novel adaptive interference mitigation scheme that can significantly reduce it. The theoretical analysis is further validated through numerical simulations.
期刊介绍：
The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
