A Note on Reliable Full-Duplex Transmission over Half-Duplex Links A simple procedure for achieving reliable full-duplex transmission over half-duplex links is proposed. The scheme is compared with another of the same type, which has recently been described in the literature. Finally, some comments are made on another group of related transmission procedures which have been shown to be unreliable under some circumstances. CACM May, 1969 Bartlett, K. A. Scantlebury, R.
