<p><P>PROBLEM TO BE SOLVED: To provide a communication ranging complex system, etc. which can efficiently and highly accurately perform transmission of information and ranging irrespective of a modulation system of a communication frame. <P>SOLUTION: In a communication ranging complex system, a master unit 3 transmits a first pulse signal to a slave unit 4 after transmission of a control frame (after first transmission timeα), and the slave unit 4 transmits a second pulse signal to the master unit 3 after reception of the control frame (after second transmission timeβ). Then, the master unit 3 calculates time (stand-by time Tm) from transmission timing of the first pulse signal to reception timing of the second pulse signal, and the slave unit 4 calculates time (response time Ts) from reception timing of the first pulse signal to transmission timing of the second pulse signal. Thus, it is unnecessary to precisely detect transmission and reception timing of the control frame, and even when a lag is generated in the first transmission timeαand the second transmission timeβ, calculation of the stand-by time Tm and the response time Ts is not affected if only edges of the pulse signals can be detected. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
