Abstract

Digital Radio Communications Systems (DRCSs) for the deployment of, and communications with, servicemen are becoming more common. The DRCS involves a large number of remote, hand-held terminals which communicate with a central station controller (CSC) over one or more shared radio frequency (RF) channels. All data is preferably digital in nature and is transmitted in blocks, or "packets," not to exceed, for example, a predetermined block size (e.g., 256 bytes). However, classical access methods are inefficient where the number of devices sharing a communication channel is high.
