Abstract:

A communication method and system for transmitting a real data signals is provided. In one aspect, the location of a communications device is determined. At least two transmitter/receiver devices are provided. A first data signal is transmitted from the communications device to the at least two transmitter/receiver devices. The data signal is received only by both receivers in combination, and with the knowledge of the location of the communication device, time delays associated with the position of the communications device are accounted for. Alternatively, a portion of a signal is sent from each of the at least two transmitter/receiver devices to the communications device, and are combined at the communications device, whereby knowledge of the location of the communication device allows time delays associated with the position of the communications device to be accounted for. In another aspect of the present invention, a communications method and system are provided for transmitting a real data signal including a communications device and a transmitter device or a receiving device. A first data signal is transmitted from the communications device to the receiving device, or a second signal is transmitted from the transmitter device to the communications device. The first or second data signals are entirely comprised of, or at least include as representation of part of the real data, signal characteristics, such as a time slot within a time period, frequency, or amplitude. The signal characteristic(s) are representative of at least a portion of the real data signal. In still a further aspect, a system may combine a divided signal as described with respect to the first aspect of the invention, whereby one or more of the signal portions are signal characteristic(s) are representative of at least a portion of the real data signal.
