Abstract:
Quasi-likelihood algorithms to detect radio signals with unknown amplitude, initial phase and appearance and disappearance moments are investigated. The algorithms of detection without adaptation to unknown parameters and with adaptation in amplitude and initial phase are synthesized. A comparative analysis of the efficiency of the synthesized detection algorithms is presented. The influence of a priori ignorance of the initial phase of the efficiency of detection is considered.
