Method for transmitting signals from a plurality of transmitting units and receiving the signals

A data transmitting and receiving method, comprising the steps of:

• preparing M signals (M is an integral number higher than 2) respectively having a signal transmitting period as a signal width for each of N transmitting units (N is an integral number higher than 2, and N.ltoreq.M), a time length of the signal transmitting period being in common to the N transmitting units;
• alternately arranging the signal transmitting periods of the M signals and (M-1) transmission short pausing periods in a signal grouping period for each of the N transmitting units;
• calling the N transmitting units a plurality of I-th transmitting units (I is an integral number, and 1.ltoreq.I.ltoreq.N);
• adjusting the (M-1) transmission short pausing periods for each of the I-th transmitting units to a common time length which is (2*N+2*I-3) or more times as long as that of the signal transmitting period not to overlap at least one signal of each transmitting unit with any of the signals of the other transmitting units;
• placing each of the signal grouping periods within a signal transmitting cycle for each of the N transmitting units, a time length of the signal transmitting cycle being common to the N transmitting units;
• and
• transmitting the M signals spaced by the (M-1) transmission short pausing periods, of which the time length is adjusted, from each of the N transmitting units to a receiving unit every signal transmitting cycle.

• adjusting the (N-1) transmission short pausing periods for each of the I-th transmitting units to a first time length which is {2/(N-2)*(N-1).sup.i -N/(N-2)} or more times as long as that of the signal transmitting period in case of N.noteq.2;
• adjusting a first transmission short pausing period for the first transmitting unit to a second time length which is equal to that of the signal transmitting period and adjusting a second transmission short pausing period for the second transmitting unit to a third time length which is three or more times as long as that of the signal transmitting period in case of N=2;
• placing each of the signal grouping periods within a signal transmitting cycle for each of the N transmitting units, a time length of the signal transmitting cycle being common to the N transmitting units;

• transmitting the N signals spaced by the N-1) transmission short pausing periods, of which the time length is adjusted, from each of the N transmitting units to a receiving unit every signal transmitting cycle.
