Title:
DATA PROCESSOR AND METHOD FOR PROCESSING DATA
Document Type and Number:
WIPO Patent Application WO/2004/012380
Kind Code:
A1
Abstract:
A data processor comprising a DEC section receiving the data of a signal transmitted after modulation and deciding the data of a plurality of predetermined original channels and the data of a predetermined correction channel from the data of a receiving signal using the EXCLUSIVE OR of the data of a plurality of channels as the data of correction channel, an XOR section for EXCLUSIVE ORing the data of a decided channel, an SQD section for detecting the quality of received signal for each channel, and a correcting section for replacing the data of a channel having worst detection results from the SQD section by the results of EXCLUSIVE OR of data of other channel when the operational results from the XOR section are not 0. The SQD section operates the mean quality of signal and the instantaneous quality of signal and the correcting section judges a channel having a worst quality of signal with reference to the mean quality of signal and the instantaneous quality of signal.
