    A high-performance data transmission system, incorporating an efficient discrete signal set and optimum detection techniques, has been developed. Envelope-orthogonal signals in the transmitter and matched filters in the receiver are employed; the system has been given the name Orthomatch. As instrumented now, the system requires 1.6 db more power than calculated for information recovery, and requi... View full abstract»

    It is shown that where the output signal-to-noise ratio is required to be large, the oscillating limiter does not contribute any more signal-to-noise ratio enhancement than the limiter without feedback under the usual assumptions of Gaussian noise and a quasi-sinusoidal signal. However, it is possible that variation of the signal amplitude with frequency and/or nonlinear phase characteristic in th... View full abstract»

    The determination of the aspect or orientation of spin stabilized satellites is vital for the correct interpretation of scientific measurements made on these spacecraft. Aspect information is collected optically from the sun, moon and earth. Little channel capacity is generally available for telemetry of this information. Therefore, completely digital low power aspect sensing and on-board informat... View full abstract»

  • Probable Accuracy in Acquisition Aids for an Orbiting Vehicle

    Publication Year: 1963, Page(s):77 - 83

    Efficient operation of a tracking system requires that certain acquisition aids be available to each station prior to vehicle approach. One method of deriving such aids is based on extrapolation of vehicle position from a set of orbital parameters. Since in general, extrapolation errors tend to increase with time, orbital parameters must be updated periodically to provide for automatic acquisition... View full abstract»

    Increasing interest in coherent PM and FM communication systems using phase-locked demodulators has promoted the development of practical coherent diversity combining systems. Phase-locked loops can convert each received signal of a diversity system to an essentially constant frequency and phase for coherent combination prior to demodulation. When the individual signals are fading with some amount... View full abstract»

  • An Integrated "Error-Free" Communication System

    Publication Year: 1963, Page(s):92 - 98

    In the interest of more efficient operation, a system is proposed which combines the functions of command, synchronization, range, and range rate on the two-way radio link. Extreme reliability of information transfer is achieved by employing "comma-free" words which have been coded for error detection. Consideration is given to an assumed elemental error probability, corresponding to a conservativ... View full abstract»
