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 signal not overlapping with any other signal is transmitted from each of the transmitting units to the receiving unit every signal transmission cycle.
