    摘要: An apparatus and method for self-calibrating mismatching orthogonal signals and non-linearity of a circuit occurring in a mobile transceiver. For this, in a mobile terminal, a transmitter is used as a signal generator and a receiver is used as a response characteristic measurer. A base band processor calibrates mismatching signals and non-linearity in a reception side and a transmission side, based on a test signal received via the transmitter and a test signal received via the receiver.

    摘要: An apparatus and method for compensating for the frequency offset of a received signal in a receiving apparatus of a mobile communication system. In the present invention, a sine component is calculated by adding I and Q channel signals resulting from downconverting a training sequence inserted between data symbols, and a cosine component is calculated by subtracting the Q channel signal from the I channel signal. Using the cosine and sine components at two time points, tangent components for the two time points are computed and thus first and second phase values are obtained. The frequency offset is estimated by determining the slope of a second-order line derived from the first and second phase values. The frequency offset of the received signal is compensated for based on the estimated frequency offset.

    摘要: A method of channel coding a digital communication system and a device using the same is provided. The method includes quantizing analog data to digital data, the digital data corresponding to a predetermined number of digital codes; allocating channel codes to the digital codes, as a Hamming distance between a pair of channel codes corresponding to any pair of the digital codes is proportional to a difference between analog values of the pair of the digital codes; and channel coding the digital data by using the channel codes which are allocated to the digital codes to generate channel coded digital data. Accordingly, digital data, such as multimedia digital data without source coding and the like, of which information significance is different may be effectively transmitted and received.

    摘要: Disclosed is a radio frequency filter of a combline structure including a frequency cut-off circuit for cutting off a specific frequency from a frequency band having a given frequency bandwidth. The frequency cut-off circuit includes an inductive transmission line extending from the output terminal by a length determined to provide an approximate inductance corresponding to a calculated value approximate to an inductance for obtaining the specific frequency, and a capacitive element coupled to the approximate inductance provided by the inductive transmission line, so that it has a capacitance for obtaining the specific frequency. The inductive transmission line is connected to the capacitive element through a via hole formed at an end of the transmission line opposite to the output terminal, from which the transmission line extends. The invention also proposes a method for implementing the radio frequency filter.
