Title: Data communication method and reception device
Inventor: KUDO KAZUHIRO
IPC: H04L25/03
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To suppress the transmission quantity of a signal and to improve communication speed by adding a level detection pattern where logic '0' and logic '1' alternately continue to transmission data and setting a threshold based on the pattern and demodulating ASK modulated data as a reference level on a reception side. SOLUTION: A transmitter generates a level detection pattern where '0' and '1' continue for plural times, and an ASK-modulated data string is transmitted by NRZ. A receiver discriminates the level detection pattern by a predetermined level. When the completion of the reception of the pattern is discriminated, the average value of the respective levels of '0' and '1' is calculated and a prescribed threshold level is calculated. The detection level of data which is A/D-converged is compared with a threshold and is demodulated. Thus, a precise reference level in the communication state can be set, increase in transmission data quantity is suppressed without using a Manchester code and communication time can be shortened. Further, the precise threshold level is obtained and a communication distance can be prolonged.
