    We announce, with both pride and trepidation, that with this issue this publications assummes a bimonthly status. Next, the appearance of a new category of communication, called a Concise Paper, in the last issue. We have found a real need for this type of item, which falls somewhere in between the formal Contribution, which has major significance to the development of the art, and the Corresponde...

    The effect of channel errors on the output signal-to-noise ratio of a delta modulation system is theoretically investigated. Both a random error channel and a channel with burst errors are considered. The analytical results for the random error channel are shown to agree closely with experimental data. View full abstract»

    This paper describes a method of transmitter waveform generation which leads to an optimally "narrow" pulse at the receiver of a given linear time invariant digital communications channel. The resulting transmitter waveform is realizable in that it must be identically zero before t=0 . The instant at which the received pulse must have its peak may be specifi... View full abstract»

    In this paper, an analysis is made of the performance of a communications system in which a reference tone is transmitted at a frequency adjacent to the phase keyed tone. The probability of error for a maximum likelihood receiver is obtained for an m -phase system of this type in the presence of additive Gaussian noise. The most advantageous division of power ...

  • Demodulation of Single-Sideband Signals Via Envelope Detection

    Publication Year: 1966, Page(s):22 - 30

    Present day single-sideband (SSB) technology is based on synchronous demodulation, with implicit stringent stability requirements. This factor has deterred the use of SSB in some services in which it might be advantageous. There are two general ways to mitigate the stability problem: by transmitting a pilot carrier to synchronize a local oscillator, and by extracting the information signal from th...

    Programming a computer to interface with a variety of telegraph apparatus on the basis of bit serial transmission signaling codes provides a broad range of code flexibility and offers the possibility of achieving greater output rates than through conventional character-bit parallel-output. A specific application involving the interconnection of an IBM 1620 computer and Teletype Model 35 equipment ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (898 KB)

    Present day service requirements dictate greater emphasis on reliability as a system design parameter and performance measure. In this paper reliability is defined and objectives are presented for a 10-hop 250-mile short-haul microwave radio relay system. A general discussion of the sources of unreliability (outage) precedes a section on possible techniques of minimizing their effects. This is fol... View full abstract»

    Satellite communication systems are being proposed with ever-increasing frequency as integral components of many future commercial, military, and space programs. Thus, many people in all levels of engineering, management, government, and military occupations are being called upon to deliver judgments on this new mode of communications. However, there are sometimes difficulties in developing these ... View full abstract»

  • Subscriber Loop Plant of Rural Telephone Systems

    Publication Year: 1966, Page(s):56 - 63
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1006 KB)

    The subscriber loop plant of rural telephone systems is described on the basis of a nationwide sampling survey of the subscriber circuits of the REA telephone borrowers. The sample consists of 1000 main telephones drawn randomly from a universe of 1 375 000 main telephones under a statistical sampling plan. The survey provided a complete description of the plant serving each of the sampled telepho... View full abstract»

    This paper presents two methods for increasing the traffic handling capability of a communication network with a minimum cost. Although we concentrate on traffic between one pair of stations (one commodity), the first formulation can be extended to the case of k flows (or k commodities). Both methods lead to a linear progr... View full abstract»

  • Analysis of Variable Premodulation Gain in AM Baseband Systems

    Publication Year: 1966, Page(s):64 - 66
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (312 KB)

    In a multichannel transmission system for which the baseband power is proportional to the cumulative channel activity, an improvement in the perchannel SNR is possible by use of variable premodulation gain. This is an average improvement which results from maintaining the baseband signal power level at its maximum value by use of variable gain prior to modulation. For such a system the SNR improve...

    A technique for binary data transmission is described, in which each binary symbol is chosen to be a prescribed superposition of n impulses of form (\sin 2\pi Ft)/2\pi Ft , spaced at intervals 1/2F. Such superposition leads to more than two received levels with binary input, but in return permits realization of the Nyquis... View full abstract»

    In the above-named work it is argued that Weaver [ibid., vol. CS-I0. pp. 91l-101, March 1962] uses the criterion of error probability to compare several PCM modulation- demodulation schemes. His curves of error probability vs. signal-to-noise ratio for maximum likelihood detection of PCM-AM and discriminator detection of PCM-FM differ markedly from other published results. In both cases, the diffe... View full abstract»

    In a previous paper, this author developed an expression for the intermodulation distortion generated in single-sideband (SSB), amplitude modulation (AM) systems carrying frequency-division multiplex (FDM) telephony, due to AM/PM conversion. For the purpose of the theory, the SSB signal is replaced by an equivalent system consisting of a carrier simultaneously phase and amplitude modulated. To sim... View full abstract»

    Viterbi (1964) has given ratios (SNRs) after demodulation in digital lower bounds on maximum signal-to-noise communication systems. He computes the SNRs according to Yates-Fish and Fitch, and Mayer (his references [7] and [8]), namely, the signal energy as the variance of the signal in the absence of channel noise; the noise energy as the variance of the difference between the signal actually demo...
