Patent ID: 7177368

Claim:
A method of data transmission, said method comprising: receiving at least one data value to be transferred; forming a notched radio-frequency (RF) burst according to the at least one data value; and launching the notched RF burst, wherein a bandwidth of the notched RF burst is at least two percent of the center frequency of the notched RF burst, and wherein said forming a notched RF burst includes altering, according to the at least one data value, at least one of the amplitude and phase of at least one selected component of a plurality of selected components of a RF burst, and wherein each of the at least one selected component has a bandwidth within the bandwidth of the notched RF burst, wherein said forming the notched RF burst includes attenuating the amplitude of exactly one of a pair of selected components if a corresponding data value is high, and attenuating exactly the other of the pair of selected components of the data value is low.
