Title: Command communicating system
Inventor: NAIKI TAKASHI
IPC: H04Q9/00
Filed: 1993-12-28
Abstract: PURPOSE:To improve the reliability of command communication by providing data for check in a command to be transmitted repeatedly, and changing the data for check every transmission in conformity with the order of a rule determined beforehand. CONSTITUTION:When the command of a first time is received, a check code 0B is detected, and following this, the pointer of a data table is turned to the position of 0B. When the command of a second time is received, the pointer is shifted to the next position and 0D is called out. Then, it is judged whether or not the check code of the received command matches 0D. At a receiving side, the judgement of the command received in succesion is executed one after another, and the number of times of matching to consider the command to be the correct one is set beforehand on a program. Accordingly, the check data of the command transmitted repeatedly is changed successively every transmission, and there is little possibility that the command to be changed in conformity with a prescribed rule appears suddenly from the outside, and the reliability of the command communication is improved at this rate.

Title: Biphase modulation transmitter-receiver
Inventor: MIYANO TAKESHI
IPC: H04L27/227
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To reproduce correctly a reference carrier signal in inverse modulation. SOLUTION: In the biphase modulation transmitter-receiver that sends/receives information data, a transmitter 10 shifts pseudo noise data for a prescribed period by 90 deg. with respect to biphase-modulated information data and synthesizes the shifted data with the information and transmits the resulting data. A receiver 20 applies inverse-modulation to a modulation signal obtained by applying synchronization detection to the received signal to generate a reference carrier signal. A pseudo noise generator 25 generates the same data as pseudo noise data in the transmitter with a prescribed phase shift and uses the pseudo noise data with the confirmed phase to apply inverse-modulation to the reception signal so as to generate the reference carrier signal.  A correlation device 24 checks the correlation between the pseudo noise data with a prescribed amount of phase shift from the pseudo noise generator and the pseudo noise data obtained through synchronization detection and discriminates that the phase of the pseudo noise data of the pseudo noise generator is confirmed when the correlation is higher than a prescribed value or over.
