    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 parallel push-pull amplifier using a complementary device, which basically operates for a B or AB-level amplification while having a common source configuration, thereby being capable of amplifying the full wave of an input signal without any distortion while obtaining a high gain at a radio frequency. The complementary device consists of an active element for amplifying a half wave of an input signal and a complementary active element for amplifying the other half wave of the input signal. The complementary active element has a duality with respect to the active element. The amplifier also includes bias circuits adapted to set respective operating points of the active and complementary active elements. Where the active and complementary active elements constitute a CMOS device, they are connected together in the form of a push-pull connection using a common source type configuration. Where the active and complementary active elements constitute a BJT, they are connected together using a common emitter configuration. This amplifier takes only the advantages of both the existing -source follower configuration and common source configuration while eliminating the disadvantages of those configurations, thereby achieving a high efficiency and a high linearity. Accordingly, it is possible to provide a power amplifier capable of obtaining a sufficient power gain even at a radio frequency.

    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.
