A spreading code protocol utilizing an echo from the receiver

Abstract

A spreading code protocol for a spread spectrum packet radio network that involves the transmission of a synchronization sequence by the transmitter and the transmission of an echo by the receiver back to the transmitter during a link setup process is introduced. Due to the added complexity, the protocol is appropriate for networks with a relatively small number of terminals. As a result of the overhead incurred by the setup minipacket, the protocol will have high efficiency for a system with low data-rate transmitters and a large ratio of the packet transmission time to the propagation delay. Throughput results are given for two spreading code protocols.<>
