Abstract
N signals are transmitted from each of N transmitting units to a receiving unit every signal transmission cycle (N.gtoreq.2). In this case, N signal transmitting periods of N I-th signals and (N-1) I-th transmission short pausing periods for each of the I-th transmitting units are alternately placed in each of I-th signal grouping periods (1.ltoreq.I.ltoreq.N), and an I-th transmission long pausing period follows each of the I-th signal grouping periods to set one signal transmission cycle composed of one I-th signal grouping period and one I-th transmission long pausing period for each of the I-th transmitting unit. A time length of each first transmission short pausing period is equal to that of the signal transmitting period, a time length of each I-th transmission short pausing period is (2N+2I-5) times as long as that of the signal transmitting period, and a time length of the signal transmission cycle is 4N(N-1) times as long as the signal transmitting period. Therefore, there is no probability that two or more signals for the j-th transmitting unit overlap with two or more signals for the k-th transmitting unit (1.ltoreq.j.ltoreq.N, 1.ltoreq.k.ltoreq.N), and at least one sig…
