SEQUENTIAL TRANSMISSION OF DIGITAL INFORMATION WITH FEEDBACK

Open-ended Terms: IBM709 Computer. The asymptotic error-correcting capability of several types of sequential transmission and the examination of a particular sequential transmission scheme are given. In sequential transmission schemes, as in one-way communication, there are two general approaches to the encoding of information for transmission over a noisy channel. The information or message sequence (which we assume is a binary sequence in which each digit carries one bit of information) can, on the one hand, be divided into blocks of fixed length, which are then encoded as separate units. Alternatively, the transmission process may be a continuous one, in which bits are introduced into the encoder, and later decoded, individually. The term decision feedback is reserved for blocktransmission systems in which a code word of indefinite length is assigned to each possible message block. (Author)
