    Experience with the use of formal descriptions of communication services and protocols is described. The paper focuses on the experience of the authors with the extended state transition model which is proposed as a standard formal description technique (FDT) for the services and protocols in the OSI environment. The first part of the paper refers to various example specifications, including trans... View full abstract»

  • Error Rate Bounds for Differential PSK

    Differential phase-shift keying (DPSK) and coherent phase-shift keying (CPSK) are two of the techniques widely used in digital communications over channels such as satellite, terrestrial radio, and voiceband telephone. Because of the linear nature of the demodulation process in CPSK, the error performance of CPSK with various sources of impairments has been exhaustively treated, but even with addi...

    We develop and evaluate motion compensation schemes for predictive coding of the component color television signal. Algorithms are discussed for estimation of motion of each color component (luminance and chrominance) separately as well as in combination. Techniques for switching of the predictors for individual components are proposed and simulated. Simulations show that it is sufficient to estim... View full abstract»

    In this paper we investigate the combined effect of sampling offset and phase error on the probability of error Peperformance of quadrature partial response (QPR) and offset QPR systems. The Gram-Charlier series expansion method is used to get accurate probability of error expressions. As an example, class 1 and class 4 partial response signaling schemes are examined.

  • A Semi-Empirical Formula for Microwave Depolarization Versus Rain Attenuation on Earth-Space Paths

    A simple semi-empirical relation is proposed to predict depolarization statistics on earth-space paths from rain-attenuation data for any given polarization and elevation angle, and for frequencies from 10 to 30 GHz. This formula is first justified by theoretical calculations, and then by extensive comparisons to measured data which show good agreement. In contrast to the CCIR approximate formula,...

    This paper attempts to lend perspective to several different methods that have been employed for specifying computer communication protocols by comparing a spectrum of specification techniques. The paper characterizes specification languages such as state transition diagrams, variants of temporal logic approaches, and sequence expressions by the extent to Which information is encoded as properties...

    After a brief introduction to the theory of Petri nets, the ECMA transport protocol is presented. Then a model of the connection and disconnection phases is developed. Properties of correctness are demonstrated, using Petri net theory results, namely, reductions and linear invariants techniques. Predicate/transition nets are introduced and the underlying network service is modeled. Then a model of... View full abstract»

  • Performance of Coherent PSK and DSPK Systems in an Impulsive and Gaussian Noise Environment

    General probability of error expressions of coherent PSK and differentially coherent DPSK systems in the presence of both impulsive and Gaussian noise are derived. The presented impulsive and Gaussian channel disturbance is a first-order approximation to operational multichannel satellite and terrestrial microwave systems in which in addition to front-end Gaussian noise, out-of-band intermodulatio...

  • Generation of Constant Envelope Signals

    In a paper, "Constant Envelope Bandlimited BPSK Signal," Yazdani et al. introduced a technique for the generation of a constant envelope signal by the addition of separately generated inphase and quadrature signals. Their scheme utilizes a nonlinear approximation to the quadrature signal ahd requires hard limiting to achieve a constant envelope. This correspondence suggests an alternate approach w...

  • Stream Traffic Communication in Packet Switched Networks: Destination Buffering Considerations

    In this paper we consider the problem of sending a stream of data (speech, for example) through a packet-switched network which introduces variable source-to-destination delays for different packets of the stream. Ideally, this delay difference should be smoothed so as to preserve the continuity of the stream. We investigate an adaptive destination buffering scheme which may be used to achieve the...

    Let M and N be two communicating finite state machines which exchange one type of message. We develope a polynomial algorithm to detect whether or not M and N can reach a deadlock. The time complexity of the algorithm is View full abstract»
