DECODER AND RECEIVER USING DIGITAL TRANSMISSION SYSTEM |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To improve transmission characteristics in various modulation methods having a plurality of amplitude levels. <P>SOLUTION: A decoder (26) includes: a transmission signal constellation signal extraction part (252) which extracts a signal point of a known transmission signal constellation signal from a signal having passed through a transmission path; a transmission signal constellation signal averaging part (253) which generates an averaged point of a transmission signal constellation signal where the signal point of the transmission signal constellation signal is averaged; an adaptive equalization part (256) which generates an adaptive equalization signal in which a waveform distortion yielded on a transmission path is suppressed by setting the signal having passed through the transmission path to the arranged point of the transmission signal constellation signal as a target convergence point; and an error collection decoding part (251) that corrects an error in the adaptive equalization signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
