| 主权项 | 1. A transmission apparatus for a wireless device, comprising: an antenna for receiving an original signal and for backscattering a modulated signal containing information from the wireless device; a variable impedance coupled to the antenna, the variable impedance having an impedance value; and, a decoder coupled to the variable impedance for modulating the impedance value, and thereby a backscattering coefficient for the antenna, in accordance with the information to generate the modulated signal; wherein the information is an N-bit digital waveform; wherein the N-bit digital waveform is applied to the decoder to produce a control signal for the variable impedance that is related to the N-bit digital waveform; and, wherein a change in the impedance value backscatters the original signal to produce the modulated signal, the modulated signal being a frequency offset form of the N-bit digital waveform. | ||
