Sonar Signal Decryption with Matched Filter

February 2022
EN.520.214 Signals and Systems

Objectives:

  • Use MATLAB to create a sinusoidal matched filter to apply on a sonar signal with additive noise
  • Decrypt the various character messages tranmitted by the sonar signal
  • Test the maximum gain of the additive noise possible that allows correct character decryption

    • Skills Applied:

  • MATLAB signal processing and control loops
  • Pair work with classmate

    • Comments:
