    摘要: Disclosed is a method and an apparatus for self-calibrating a Direct Current (DC) offset and an imbalance between orthogonal signals, which may occur in a mobile transceiver. In the apparatus, a transmitter of a mobile terminal functions as a signal generator, and a receiver of the mobile terminal functions as a response characteristic detector. Further, a baseband processor applies test signals to the transmitter, receives the test signals returning from the receiver, and compensates the imbalance and DC offset for the transmitter side and the receiver side by using the test signals. The test signal is applied to only one of the I channel path and the Q channel path, and an RF band signal output from the transmission side by the test signal is used as an input signal to the reception side.

    摘要: A method is provided for self-calibrating the mismatch and the direct current (DC) offset occurring in a mobile transceiver. The transmitter of the mobile terminal is used as a signal generator and the receiver thereof is used as a response characteristic measurer. The baseband processor calibrates the mismatch and the DC offset for the receiving and transmitting sides using a test signal received from the transmitter. When multiple input subcarriers are used in a mixer present on a reception stage, self-calibration is performed using multiple received test signals obtained from one transmission test signal.

    摘要: An iterative decoder and iterative decoding method. In the iterative decoder, a first adder has a first port for receiving information symbols and a second port. A first component decoder which is coupled to the first adder, receives first parity symbols and decodes the information symbols using first parity symbols and an output signal of the first adder. A first subtractor has a third port for receiving the output of the first component decoder, and a fourth port. An interleaver which is coupled to the output of the first subtractor, interleaves the decoded information symbols received from the first component decoder. A second component decoder receives the output of the interleaver and second parity symbols and decodes the information symbols of the interleaver output using the received signals. A deinterleaver deinterleaves the output of the second component decoder. A second subtractor has a fifth port for receiving the output of the deinterleaver and a sixth port for receiving an inverted output of the first subtractor. The output of the second subtractor is connected to the second port and an inverted output of the second subtractor is connected to the fourth port. A hard decision device converts the decoded symbols received from the first component decoder to binary information bits. An error detector checks errors in the binary information bits received from the hard decision device and generates a no error signal if no errors are detected. An output buffer stores the binary information bits received from the hard decision device and outputs the stored binary information bits in response to the no error signal.
