    The authors formerly made a report on a direct vision type direction finder for high frequency, which has high sensitivity and by which multiple signals or scattering signals can also be measured. Since then, the finder has been used for studying characteristics of the ionospheric propagation waves. In order to make continuous measurement of bearing convenient, a recording apparatus adaptable to t... View full abstract»

    In narrow-band transmission of television or radar over telephone lines it is necessary to use a carrier system to avoid phase distortion normally present at the lower end of the transmission band. Using ordinary modulation and demodulation techniques, the usable video bandwidth is limited to one-half the carrier frequency. In the limiting case in which the carrier is placed at the extreme upper e... View full abstract»

  • Comparison of PSK vs FSK and PSK-AM vs FSK-AM Binary-Coded Transmission Systems

    The performance of phase shift keyed (PSK), frequency shift keyed (FSK), PSK amplitude modulation (PSK-AM), and FSK amplitude modulation (FSK-AM), systems are compared for binary coded transmission in the presence of additive white Gaussian noise. This performance is based on the relative probability of error, operating range, required system bandwidth, and system frequency instability. The import... View full abstract»

    The problem of nonconservation of message length in a decision-feedback system arises as a result of noise in the feedback channel. A system is considered which avoids this by requiring all corrections to be transmitted during specified intervals. The decision mechanism of the receiver is based on the structure of a modified Slepian code, and several final decision schemes are analyzed and compare... View full abstract»

    Several point-to-point systems have demonstrated successful communications while employing propagation via meteor trail reflections at very high frequencies. However, few systems have been able to control the output error rate in the presence of sporadic E and auroral phenomenon. Nevertheless, early results clearly indicated the strong potential of the meteor m... View full abstract»

    This paper discusses the actual performance of a 2500 bit per second data modem under simulated conditions in the laboratory and actual conditions on 27 different voice frequency wire lines. Under simulated conditions, it was determined that an error rate of one in 106can be maintained with a signal-to-white noise of 14.5 db. On actual line tests for over 200 hours, the error rate was a... View full abstract»
