An electronic device according to the present disclosure may include: a housing including a substantially transparent plate that includes a first surface facing in a first direction, and a second surface facing in a second direction; a display exposed in the first direction; and a camera device exposed in the first direction. The camera device may include: a barrel structure including a side wall defining a space therein and an opening facing the first direction and a camera housing structure including a side portion surrounding at least a portion of the side wall of the barrel structure and an upper portion facing the first direction. The camera housing structure may include a first protrusion formed on the upper portion. The present disclosure implements a waterproof/dustproof structure for capping at least a portion of the camera device.

A method and mobile device for decoding a paging message transmitted as multiple bursts in a wireless communication system are provided. In the method, only the first burst among four bursts of a transmitted paging message is received and equalized. The equalized first burst is compared (e.g., by computing correlation) with a reference paging message. The first comparison result value obtained from the first comparison is compared with a threshold value. If the first comparison result value is greater than the threshold value, second through fourth bursts of the paging message are not received, and a previous decoded paging message is output and a sleep state is entered. If the comparison result value is not greater than the threshold value, the second through fourth bursts are received and decoded, the decoded paging message is encoded, and a first burst of the encoded paging message is stored as the reference paging message.

Method and apparatus for decoding paging message in wireless communication system

A method of decoding a control channel in a wireless communication system is provided. In the method, a terminal calculates the number of sub-bursts to be used during a next decoding and positions of the sub-bursts, based on a signal-to-noise ratio of at least one of a first burst or a second burst. Then, the terminal compares the calculated number of sub-bursts with a reference value. When the calculated number of sub-bursts is greater than the reference value, the terminal does not receive more bursts or sub-bursts and instead enters into a sleep state. When the calculated number of sub-bursts is smaller than or equal to the reference value, the terminal receives and decodes only sub-bursts at the calculated positions.

A method of reducing a number of computations in an equalization process includes performing a pre-equalization operation on selected first frames from a plurality of frames, and estimating pre-equalization values of second frames based on the pre-equalization values of selected first frames, the second frames being frames which are not selected from the plurality of frames.

A degrouping method for an MPEG 1 decoder for degrouping three consecutive subband samples (X, Y and Z) compressed into one codeword .COPYRGT. by a step number (N) includes the steps determining whether the value of the step number is 3, determining whether the value of the step number is 5 if the value of the step number is not 3, determining whether the value of the step number is 9 if the value of the step number is not 5, searching corresponding values of the subband samples from a first look-up table in the sequence of Z, Y and X, if the value of the step number is 3, searching corresponding values of the subband samples from a second look-up table in the sequence of Z, Y and X, if the value of the step number is 5, and searching corresponding values of the subband samples from a third look-up table in the sequence of Z, Y and X, if the value of the step number is 9, wherein the first, second and third look-up tables have the respective values of the subband samples corresponding to the codeword value. Since the MPEG 1 degrouping method obtains subband samples using look-up tables without using a divider, the number of required cycles is considerably reduced.
