Some possible criteria for estimating the effectiveness of correcting codes are presented, and the energy effectiveness of correcting codes is studied for symbol-by-symbol reception. Expressions for the energetic effectiveness of binary correcting codes for reception in the whole are produced. Asymptotic energetic effectiveness and finite signal/noise ratio cases are considered.
An approach to data compression is discussed in which the effect achieved by compression is evaluated by the closeness of the approach to the minimum possible volume. An attempt is made to systematize the known results on data compression. The review contains: description of methods of data compression based on statistical coding and information theory; application of methods of interpolation and extrapolation; a specific compression method (related to description of the histogram of a sample); some criteria of effectiveness and methods of service information representation; and discussion of models suggested for theoretical analysis.
Two modifications of the method of frame synchronization by means of a frame pause were studied. The first does not require that all characters in the frame pause follow each other immediately. The second modification is based on the use of one particular type of redundancy within the frame to achieve frame synchronization without setting aside a special frame pause. Concentrated, distributed and combined frame pause are described and their uses compared.
