THE COMBINED USE OF PULSE ATTRIBUTES IN PRO TECTED CIRCULAR SIGNALS
Abstract
The combined use of pulse attributes in protected circular signals was investigated. To transmit information concerning the state of M two position objects in one signal (i.e., for circular transmission in a group), it is necessary to have 2(M) signals, each of which corresponds to one of the combinations of states of the objects of the group. The combined use of pulse attributes is more advantageous than the use of one pulse attribute for circular transmission. Circular transmission may be accomplished with the aid of systematic codes by a sampling method close to distributional. In the circular method of transmission, protection from distortions may be realized both by the method of protective refusal and through error correction. In the case of two-position objects it is con venient to use signals made up of only complete combination elements. In the case of multi position objects it is convenient to use in complete combination elements.
