Abstract:
Provided is a bus signal encoding/decoding method and apparatus. The bus signal encoding method includes receiving a bus signal, XOR-operating all but the first byte sequence of the bus signal in a bitwise manner, inverting the even-numbered byte sequences of the XOR-operated bus signal in a bitwise manner, and serializing the inverted bus signal.
Abstract:
An image forming apparatus including: a reflection member to reflect light at a first position spaced a predetermined distance from a scan glass; a moving unit to move the reflection member between the first position and a second position; and a control unit to generate initial reference data from an image signal transmitted from a scanning device to receive the light reflected by the reflection member. When the initial reference data is not suitable for shading correction, the control unit controls the moving unit to move the reflection member to the second position for reference data reacquisition.
Abstract:
Disclosed herein is a method for generating a test signal for testing the accuracy of the CINR measurement of a subscriber station. The method includes step (a) of checking a preamble code corresponding to a predetermined cell ID, reading corresponding preamble data from a preamble code table, and taking it as desired preamble data, step (b) of completing generation of desired signal data by generating desired pilot data and various information data, step (c) of randomly selecting one preamble code from among preamble codes corresponding to cell IDs other than the cell ID, reading corresponding preamble data from the preamble code table, and taking the preamble data as interference preamble data, step (d) of generating interference pilot data, and step (e) of generating test signal data by adding the interference preamble data and the interference pilot data to the desired signal data.
