Communication systems with usage of a ternary code.

The losses in multichannel systems of a radio communication are defined(determined) by reliability and duration of signals, transmitted on communication channels, [1,2] Duration of signals at fixed channel parameters of communication(connection) is defined(determined) by quantity of information digits, and also aspects of encoding (conversion of information digits). All computer technology works with binary codes, which one are badly fitted to transmission(transfer) on communication channels [3,4]. In this connection virtual velocity of transmission(transfer) is not high and d oes not exceed 12 %, 46 % from actual transmission rate in a system [7]. A reason it is the great many of a service information, into which one fall the synchronizing informationand as the exuberant digits entered for detection and an errorcorrection At the same time, are theoretically justified advantages of an information communication from the help of a ternary code. However practical implementation of this code till now misses. The writer has elaborated a converter of the binary information in a ternary code, which one allows to realise an information communication in a communication channel with information rate. The algorithm of such conversion is encompass byed volume, that in case of transmission(transfer) of a packet of identical digits of a binary code each even digit is substituted by a digit of repetition [8,9]. At such conversion all digits, transmitted in a communication channel, have identical duration, that allows by the supervision of their duration to detect all errors, in a received codegram. Such conversion does not change duration of an information array, i.e. saves information transmission rate. The initial information sequence allows to establish N = 2 ^ (n_k) code patterns - where n_k- quantity of information digits in a mass data. After conversion in a ternary code of obtained combinations will be N =? (3)? ^ (n_k), i.e. after conversion we obtain a code pattern with redundancy D =? (3/2)? ^ (n_k) =? (1,5)? ^ (n_k) which one is defined(determined) by its(her) duration. In this connection there is a possibility of an errorcorrection, the maximum quantity which one is equal to half of code word length [8,9]. The errorcorrection descends practically without time delays of the received information, and the complexity of the device error-correcting, does not depend from are long code patterns and will be realised very simply. Thus, have received a way of conversion of the binary information in a ternary code, which one allows at an information communication on communication channels to realise following advantages: To detect all errors by the supervision of duration of a digit, as the duration of all digits is identical; Ensures heightened accuracy of synchronization, as the synchronizing information transmits with each digit and two fronts (back previous and front consequent digit); The maximum quantity of patched(rectified) errors reaches half of quantity of digits in a codegram; The errorcorrection demands a delay of the information all on two digits, and the time delay does not depend on a code word length, that is specially important for navigation systems, in which one signal delay reduce in errors of position of determination; The complexity of the device of an errorcorrection does not depend on quantity of digits in a codegram; The ternary code allows to receive a prize in 6 дб on a signal/noise ratio, that considerably exceeds a similar value 0,6 дб by transmission(transfer) of the binary information by the Hamming code (10). 7) In view of absence of a padding service digits the transmission capacity of transmission systems of the digital information can be magnified in 2-8 times because at ternary conversion there are exuberant digits (in hardware systems an information information rate [5] lies in limits from 12 % up to 46 % from technical). In summary it is possible to say, that any of existing transmission modes of the information has no such properties, and the writer repeatedly has realised it(him), both in laboratory preliminary samples, and in a hardware product, elapsed state official tests.
