Various embodiments disclosed in the present document relate to an accessory and a manufacturing method therefor. Various embodiments disclosed in the present document may provide an accessory comprising: a base structure which comprises a plate having a front surface facing in a first direction and a rear surface facing in a second direction opposite to the first direction, and a side member extending from the edge of the plate; a first cover member which at least partially covers the surface, including the rear surface, of the base structure and comprises a first flat portion placed opposite to the rear surface, a first edge portion placed opposite to the outer surface of the side member, and a first hemming portion placed opposite to at least a part of the inner surface of the side member; and a second cover member which at least partially covers the surface, including the front surface, of the base structure and comprises a second flat portion placed opposite to the front surface, and a second edge portion placed opposite to at least a part of the inner surface of the side member, wherein at least a part of the second edge portion overlaps at least a part of the first hemming portion.

Accessory and manufacturing method therefor

The present disclosure relates to an apparatus and a method for transmitting a signal using a power amplifier in a wireless communication system in which a transceiver comprises a digital pre-distorter configured to distort an input signal based on a distortion control value, a power amplifier configured to amplify an output signal from the digital pre-distorter, an antenna configured to transmit an output signal from the power amplifier, an echo signal canceller configured to remove an echo signal which returns to the power amplifier due to a return loss of a path between the power amplifier and the antenna, from a feedback signal obtained at an output stage of the power amplifier, and a digital pre-distortion adaptation unit configured to determine the distortion control value based on an output signal from the echo signal canceller.

Apparatus and method for transmitting signal in wireless communication system

A base station for cancelling a transmitter noise present in a reception band, according to the embodiment of the present invention comprises: a transmitting and receiving unit for transmitting and receiving a signal; an uplink signal detector for detecting a first signal extracted from a reception path of the base station and a second signal extracted by filtering, on the basis of the reception band, a signal transmitted on a transmission path of the base station, and for determining, on the basis of the detection result, whether an uplink signal transmitted from a terminal is included in the first signal; and a processor for determining whether to cancel the transmitter noise depending on whether the uplink signal is included in the first signal.

Base station for cancelling transmitter noise present in reception band and method for operating same

A method for removing a peak of an input signal includes forming a peak group including multiple peaks having an amplitude greater than a preset signal threshold value in the input signal, generating a cancellation pulse corresponding to the peak group, and generating a output signal by subtracting the cancellation pulse from the input signal.
