Datenübertragungsvorrichtung mittels Streuspektrum-Kommunikation

摘要

In response to a bit transfer request from one of two units, bit data is transmitted bit by bit from the other of the two units. The unit on the transmission side for transmitting the bit data has an M-series generator. In response to bit 1, a first M0-series signal of a 63-word length is generated. In response to bit 0, a second M0-series signal in which the series start position is set to the intermediate position of the first M0-series signal, although the signal is the same M0-series signal of the 63-word length, is generated. The unit on the reception side has previously stored the first and second M0-series signals on the transmission side as reference signals, and calculates the correlations between the two reference signals and the reception signal, and demodulates the data bit corresponding to the reference signal having a larger correlation value.
