This study introduces orthogonal frequency coding (OFC) for surface acoustic wave (SAW) sensors, enabling wireless, passive operation in multisensor environments. OFC enhances sensor identification and data retrieval, offering advantages like spread spectrum communication benefits.

Area of Science:

  • Sensor Technology
  • Wireless Communication
  • Signal Processing

Background:

  • Surface acoustic wave (SAW) sensors provide wireless, passive operation.
  • Multisensor environments require unique sensor identification and data retrieval.
  • Existing single-sensor systems lack robust multisensor identification capabilities.

Purpose of the Study:

  • To introduce and evaluate orthogonal frequency coding (OFC) for SAW sensor applications.
  • To demonstrate OFC's effectiveness in multisensor identification and data retrieval.
  • To explore the advantages of OFC in spread spectrum communication for SAW sensors.

Main Methods:

  • Implementation of orthogonal frequency coding (OFC) for SAW sensor tagging.
