Abstract: An asymmetric bandwidth communication system enables wireless communication between interrogators/ readers and transponders/ tags. A transponder transmits TDCIR (Time Domain Carrierless Impulse Radio) signals in the uplink direction and receives non-TDCIR signals, such as electromagnetic continuous waves, in the downlink direction. The transponder may receive partial or whole power from non-TDCIR signals. The TDCIR utilizes electromagnetic impulses with short duration and ultra wide bandwidth. It offers high data rate reliable communication at low power and design complexity. It also demonstrates resilience against path fading, selective absorption and reflection by physical matters and excellent location determination capabilities.

Abstract: The present invention is a method and an apparatus to use carrierless signals for energizing remote passive or active transponders (tags) and for communication link between a reader and the transponders. The reader's transceiver generates very short high power pulses to transmit them to the transponder which receives and stores the pulse energy in an energy store on the transponder. At the transponder the power pulse signal is compressed by a matched filter and rectified. Information to be transmitted from the reader to the transponder and from the transponder to the reader can be added to the data pulses by means of pulse position modulation, bi-phase modulation or other well-known wide-band modulation techniques. The communication is active as the transponder utilizes stored power for transmission and reception of signals while the transponder can be passive and is powered by the reader's signal energy.
