We studied the quasi-likelihood and quasi-optimal algorithms for estimation of the moments of appearance and disappearance of the radio signal with rectangular envelope and unknown amplitude, initial phase and carrier frequency. We synthesized the quasi-likelihood estimation algorithm with the adaptation to the amplitude and the initial phase. The block diagram was proposed for obtaining the required estimates. We analyzed the introduced algorithm and found the asymptotically exact (with increasing a signal-to-noise ratio) expressions for biases and variances of the estimates of the moments of appearance and disappearance. We also proposed the quasi-optimal algorithm for estimation of the moments of appearance and disappearance. It was shown that its application allows us to simplify the hardware and software implementation of the estimation procedure.
