Claims

1. THE METHOD OF SIGNALING ON A SINGLE CARRIER FREQUENCY WHICH COMPRISES THE STEPS OF OBTAINING A PLURALITY OF INFORMATION SIGNALS TO BE TRANSMITTED FROM DIFFERENT LOCATIONS PROVIDING DIFFERENT SIGNAL PROPAGATION TIMES BETWEEN LOCATIONS, RESPECTIVELY TIME COMPRESSING SAID INFORMATION SIGNALS, SEQUENTIALLY TRANSMITTING WITH A SINGLE CARRIER FREQUENCY EACH RESPECTIVE ONE OF SAID COMPRESSED INFORMATION SIGNALS FROM SAID RESPECTIVE LOCATIONS DURING A PORTION ONLY OF A RESPECTIVE ONE OF A PLURALITY OF CHANNEL PERIODS OF A SAMPLING CYCLE PROVIDING A DEAD TIME BETWEEN COMPRESSED SIGNALS DELIVERED DURING ADJACENT CHANNEL PERIODS TO LIMIT INTERFERENCE BETWEEN SAID SIGNALS DUE TO VARIATIONS IN TRANSMISSION TIME, AND RECEIVING SAID SIGNALS WITHIN THEIR SAID SELECTED CHANNEL PERIODS AT A LOCATION PROVIDING VARIATIONS IN TRANSMISSION TIMES BETWEEN SAID SIGNALS.
