    摘要: A repeater having different input and output frequencies converts a signal received with the input frequency to a first intermediate frequency signal based on a local oscillating frequency for intermediate frequency conversion, and converts the first intermediate frequency signal to a second intermediate frequency signal by performing digital processing on the first intermediate frequency signal. Then, the repeater generates a first frequency tone signal that corresponds to a difference between the input and output frequencies, and generates a second frequency tone signal from the local oscillating frequency for intermediate frequency conversion and the first frequency tone signal. The repeater up-converts the second intermediate frequency signal to the output frequency based on the second frequency tone signal, and transmits the signal.

    摘要: Provided is a method for searching for an optimal coder suitable to a dual stream transmission method of a DTV transceiving apparatus, and an encoder and a decoder employing the optimal coder searching method. The optimal coder searching method includes the steps of: a) determining a mixed pattern of normal stream and robust stream; b) determining a trellis structure of the robust stream which is applied to the mixed pattern based on how coders are connected; c) forming a dual stream trellis by mixing a trellis of the normal stream, which is a normal stream trellis, and a trellis of the robust stream, which is a robust stream trellis; d) computing a free distance at departing points of the dual stream trellis structure based on a dual stream free distance computation termination condition; and e) determining the optimal coder based on the free distance.
