  • Patent number: 11936417
    Abstract: The present invention relates to a time-division duplex (TDD) antenna apparatus which can reduce signal loss, and thereby minimize the noise figure (NF) of a system and extend uplink coverage of the system, by separating a transmitter circuit from a receiver circuit of the antenna apparatus, and disposing a low noise amplifier (LNA) of the receiver circuit between a reception antenna and a reception filter of the receiver. A time-division duplex antenna apparatus according to an embodiment of the present invention includes: a transmitter which includes at least one transmission antenna module and transmits a downlink signal through a first path; a receiver which includes at least one reception antenna module and receives an uplink signal through a second path that is separated from the first path without any overlapping portions thereof; and a controller which controls the transmitter and the receiver in a time-division duplex manner.

  • Publication number: 20240067208
    Abstract: There is provided a VIL system-based autonomous driving function verification method. According to embodiments of the disclosure, a VIL system enables an autonomous vehicle to verify an autonomous driving function by interlocking with a virtual road environment in any other place, without having to go to a real test road corresponding to a simulated virtual road environment. Accordingly, an autonomous driving function can be rapidly verified based on a VIL system with respect to various virtual road environments without changing a driving place, so that speed and convenience in development of autonomous driving technology can be enhanced.
