摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method and apparatus for channel estimation and equalization in a cellular environment based on quadrature amplitude modulation-filter bank multicarrier (QAM-FBMC) transmission is provided. The signal transmission method for a transmitter includes sending channel measurement information to a receiver, receiving channel related information from the receiver, selecting a first filter and a second filter to be used for signal transmission according to the received channel related information, mapping, when no performance difference is present between the first filter and the second filter, reference symbols evenly to subcarriers associated with the first filter and subcarriers associated with the second filter, mapping, when a performance difference is present between the first filter and the second filter, reference symbols preferentially to subcarriers associated with the transmitting filter with higher performance, and sending a transmit signal having the mapped reference symbols.

摘要： Provided is an image encoding method including generating a first picture reconstructed by using a residual picture and a predicted picture; generating a second picture by applying a first artifact reduction filter to the first picture; determining a picture having a smaller bit-rate distortion cost from among the first and second pictures by comparing a first bit-rate distortion cost of the first picture with a second bit-rate distortion cost of the second picture; generating a third picture by applying an in-loop filter to the determined picture; generating a fourth picture by applying a second artifact reduction filter to the third picture; determining a picture having smaller distortion from among the third and fourth pictures by comparing first distortion of the third picture with second distortion of the fourth picture; and generating, via a processor, a bitstream including information about whether the second artifact reduction filter is applied.

摘要： Disclosed is a display apparatus capable of preventing and/or reducing overheating of driving switches due to a malfunction during varying of a driving voltage. The display apparatus includes: a light emitting diode; a power supply configured to apply a driving voltage to the light emitting diode; a driving switch configured to control the driving current of the light emitting diode; a voltage sensor configured to detect the driving voltage; and a driving controller configured to control the driving switch so that the driving current of the light emitting diode follows a current reference. The driving controller may be configured, based on the driving voltage detected by the voltage sensor being greater than a predetermined voltage, to decrease the current reference to decrease the driving current of the light emitting diode.
