Abstract EN
For decoding the asynchronous superposition of response signals from different sensors, it is a challenge to achieve correlation in a code division multiplexing (CDM) based passive wireless surface acoustic wave (SAW) multisensor system.
Therefore, an on-chip correlator scheme is developed in this paper.
In contrast to conventional CDM-based systems, this novel scheme enables the correlations to be operated at the SAW sensors, instead of the reader.
Thus, the response signals arriving at the reader are the result of cross-correlation on the chips.
It is then easy for the reader to distinguish the sensor that is matched with the interrogating signal.
The operation principle, signal analysis, and simulation of the novel scheme are described in the paper.
The simulation results show the response signals from the correlations of the sensors.
A clear spike pulse is presented in the response signals, when a sensor code is matched with the interrogating code.
Simulations verify the feasibility of the on-chip correlator concept.
