| Summary |
"There are many military and commercial applications in which the main objective is to monitor an intercepted digital radio signal. This thesis describes an algorithm that reliably distinguishes between six common digital modulation types. The method is based on an algorithm developed by Azzouz and Nandi that performs relatively simple calculations on the instantaneous amplitude, instantaneous phase and instantaneous frequency of the intercepted signal to determine the modulation type. Computer simulations using this method did not agree with previously published results. A modified method is presented that improves upon the recognition of four of the six modulation types considered"--Abstract, leaf iii. |
