Abstract: The present disclosure relates to a state feedback decoder based channel estimating method including: calculating a first output bit when an input bit is 0 and a second output bit when an input bit is 1 using convolution encoder state information received from a determining unit; configuring a first virtual pilot and a second virtual pilot through modulation by receiving the first output bit and the second output bit; deinterleaving an i-th (here, i refers to a natural number corresponding to the number of OFDM symbols from 1) OFDM symbol; estimating a first channel and a second channel based on the first virtual pilot and the second virtual pilot using an output value in accordance with the deinterleaving result and calculating a first mean square error (MSE) and a second MSE; and comparing the calculated first MSE and second MSE to determine an input bit having a lower MSE as a reception bit by the determining unit and updating and feedbacking the convolution encoder state information using the determined reception bit.

Abstract: Disclosed is a method of detecting obstacle around a vehicle. The method of detecting an obstacle around a vehicle, includes: acquiring an image of the obstacle around the vehicle using a monocular camera; creating, by a controller, a distance based cost map, a color based cost map and an edge based cost map from the image; and integrating, by the controller, the distance based cost map, the color based cost map, and the edge based cost map to create a final cost map, and estimating, by the controller, a height of the obstacle from the final cost map.

Abstract: Disclosed is a method for operating a communication node supporting a low power mode in a wireless LAN. A method for operating a station, which includes a PCR and a WURx, comprises the steps of: allowing the WURx, which operates in a wake-up state, to receive a wake-up packet from an access point; transitioning an operating state of the PCR from a sleep state to the wake-up state when the wake-up packet is received; allowing the PCR, which operates in the wake-up state, to receive a data frame from an access point; and allowing the PCR to transmit, to the access point, a response to the data frame.
