Abstract
The author describes an investigation into the concept of address communication systems of a form called random access-discrete address. In the literature this is also referred to as non-synchronous or asynchronous comnunication. The basic concept exploits the random character of speech so that some talkers are transmitting during quiescent periods of others. It is therefore a voice comuication system although not necessarily limited to voice. As the author has been considering the system many transmitters radiate signals more or less simultaneously, and each receiver must pick out of this mixture of signals those signals which are intended for him. Thus, the use of the phrase 'random access.' In order to accomplish this, each transmitter addresses each and every signal element which it transmits with the code of the intended receiver so that the receiver may select the coded signal addressed to it. Hence, the terms 'discrete address.'Keywords
