Abstract:
An apparatus and a method are provided for receiving a signal in a communication system supporting a Gaussian frequency shift keying (GFSK) modulation scheme. The method includes receiving the signal; and estimating a codeword vector by performing a signal detecting operation based on a GFSK-maximum likelihood sequence estimation (MLSE) scheme, which is based on a GFSK modulation scheme and an MLSE scheme, on the received signal. States of a Viterbi trellis that are used in the GFSK-MLSE scheme are determined based on the GFSK modulation scheme.
Abstract:
A method of manufacturing a pellicle includes forming a membrane on a first surface of a substrate from a chemical reaction in which the substrate serves as a catalyst, forming a protective pattern on a second surface of the substrate, immersing the substrate in an etchant solution, such that a portion of the substrate exposed through the protective pattern is removed to form a frame, and replacing the etchant solution with a solvent.
Abstract:
A wheel replacing apparatus includes a partitioning wall including opposite first and second surfaces opposite in a first direction, a motor, a transmission unit, a support extending in a second direction intersecting the first direction, a rotating unit between the support and the transmission unit, an arc-shaped portion connected to the support and having an open inner wall and a shape including a portion of a circle having a central axis extending in a third direction perpendicular to the first and second directions, a roller within the arc-shaped portion, a clamp connector extending from the support in the first direction, and a clamp connected to the clamp connector and having a curved portion. The wheel replacing apparatus is configured to adjust a spacing between the arc-shaped portion and the clamp. The rotating unit is configured to rotate around a rotating unit central axis that extends in the third direction.
Abstract:
A method of manufacturing a pellicle includes preparing a pellicle frame having an adhesive layer coated thereon, treating a pellicle membrane with vapor under vapor atmosphere, attaching the pellicle membrane onto the pellicle frame, and drying the pellicle membrane.
Abstract:
A method and electronic device for receiving information is provided. The method includes transmitting, by the electronic device, a scan time and an identification of the information to cause the identified information to be broadcast at the scan time; and scanning, by the electronic device, during the scan time to receive the information. The electronic device includes a transmitter configured to transmit a scan time and an identification of the information to cause the identified information to be broadcast at the scan time; and a scanner configured to scan during the scan time to receive the information.

Abstract:
The present disclosure relates to a method and an electronic device for processing data on the basis of a Bluetooth Low Energy (BLE) protocol. The electronic device includes a Bluetooth control module and a processor. The Bluetooth control module stores a modified BLE protocol stack including at least two Attribute Protocols (ATTs) for use with an application, the modified BLE protocol stack includes a first path and a second path. The first path includes a first ATT protocol to process an ATT command of the application, and the second path includes a second ATT protocol to process an ATT command of the application. The processor is coupled to the Bluetooth control module. The processor processes data of the application including the ATT command, using the modified BLE protocol stack including the at least two ATTs of the Bluetooth control module.
Abstract:
An electronic device that uses a method of transmitting audio data is provided. The method includes encoding first audio data of a first audio stream section included in an audio stream, encoding second audio data of a second audio stream section included in the audio stream, transmitting the encoded first audio data to a first auxiliary device, and transmitting the encoded second audio data to a second auxiliary device after a time corresponding to a predetermined interval.
