    The presence of a feedback channel makes possible a variety of sequential transmission procedures, each of which can be classified as either a block-transmission or a continuous-transmission scheme according to the way in which information is encoded for transmission over a noisy forward channel. A sequential continuous-transmission system employing a binary symmetric forward channel (but which is... View full abstract»

    A definition of a recurrent code is given in a framework which renders it amenable to mathematical analysis. Recurrent codes for both independent and burst errors are considered, and a necessary and sufficient condition for either type of error correction is established. For burst-error-correcting codes, the problem treated is (for a fixed burst length and redundancy) the minimization of the error... View full abstract»

    This paper sets up a restricted class of search procedures for a satellite lost in a region of the sky. The satellite must be found by a radar search. The procedures under consideration allow the use of a preliminary search, which may be done with a wider beam than is required for the final search. The purpose of the preliminary search is to obtain a ranking of the various portions of the sky, so ... View full abstract»

  • Iterative design of optimum filters for non mean-square-error performance criteria

    In an earlier paper,<tex>^{1}</tex>the design of filters by means of an iterative adjustment scheme was described. The filter was assumed to be of a fixed form but to contain<tex>k</tex>variable parameters. The problem is to find the parameter setting that minimizes the expectation of some weighted value of the error. The adjustment scheme was proposed because it has two ad... View full abstract»

  • Reducing the effects of intersymbol interference with correlation receivers

    This paper considers the problem of intersymbol interference in a binary communication system and the optimization of a class of linear receivers to minimize the effects of this interference. The class of correlation receivers is chosen for investigation, and maximizing the probability of correct reception is used as the performance criterion. The optimum decision level as well as optimum impulse ... View full abstract»

    In an asynchronous multiplex system a single band of radio frequencies carries many simultaneous conversations, each of which uses a distinguishable train of pulses as a "carrier." To design a good list of allowed pulse trains one is led to a peculiar kind of error-correcting code problem. The encoding sought uses binary<tex>N</tex>-tuples (code words) in which most of the digits are z... View full abstract»

    In studies of sequential detection of radar signals, the parameter of primary interest is the length of the sequential test, denoted by<tex>n</tex>. Since this test length is a random variable, moments and/or probability distribution functions of<tex>n</tex>are desirable. A procedure is described in this communication for obtaining exact probability distribution functions&l... View full abstract»

  • Rotational transformation of signals

    A coding procedure based on a rotational transformation is applied to reduce the effect of non-Gaussian impulsive noise in sampled data communication systems. The method, a near relative of the smearing techniques which have been suggested recently for continuous systems, provides a new and interesting view of many accepted coding systems and their relative properties. Attention is directed toward... View full abstract»

    The author has previously developed a new upper bound on nonsystematic binary error-correcting codes, using a sphere-packing approach and combinatorial analysis. A significant refinement is now added; together with a detailed study of the asymptotic behavior of the upper bound, this enables one to show that any large code must {\em correct} almost all sequences with a larger number of errors than ...

    Relationships are derived showing that the optimum processor for a process that has been transformed by a memoryless nonlinear device is of the same form as that for the original untransformed process if we replace the measured values of the process by their inversely transformed values.
