Synthesis of optimum receiver and processor for signal packet of radio pulses
Abstract
A quasi-coherent optimum receiver and processor for a useful signal packet of radio pulses appearing in an additive mixture with a stationary normal white noise is synthesized in accordance with the Markov theory of nonlinear filtration. In addition to a period estimator, multipliers, a differentiator, and a summator, the structure of this device includes a shaper of unit-amplitude video pulse packets, a fine-tunable carrier-frequency oscillator, and a (O, pi) phase keyer. The estimated error of period parameter filtration indicates that a packet of L radio pulses has a signal to noise ratio L times higher than a single pulse. In the extreme case of zero filtration error and a payoff of using pulse packets (M approaches the square root of L) the a-posteriori dispersion of the filtered period parameter is the square root of L times smaller in a packet than in a single radio pulse.
