Title:
DATA TRANSMISSION METHOD AND TRANSMITTER-RECEIVER
Document Type and Number:
Japanese Patent JP3137092
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique capable of correcting the error of received data and surely receiving normal data in one cyclic period even in the case that the error exists in data.
SOLUTION: At the time of transmission data preparation, a parity bit whose object is initial transmission part data (address + data), inverse successive transmission part data and the parity bit whose object is the inverse successive transmission part data for examining the error on a reception side are added. In the meantime, the data for error correction are prepared based on the initial transmission part data and the data for the error correction are transmitted at the half transmission rate of the transmission rate of the initial transmission part data. On the reception side, in the case of detecting the error in cyclic data, the logic of the larger ones of the data for the error correction, the initial transmission part data and the inverse successive transmission part data is adopted and the error correction is performed.
