Abstract
A communication protocol for a local network that handles voice signals and uses ‘direct sequence spread spectrum’ techniques ( DS-SS), is presented. The control of the protocol is distributed among the network users, providing them with the capability for full-duplex communication and successful channel acquisition without data collisions. The access of the single communication channel by any user of the network and the routing of calls are based on the detection of the number of the decoded signal levels. The implementation of the network is simplified with the use of a single code per communication. The protocol operation ( including the call scheduling and signalling processes) that generates all the signals necessary for communication in the network ( ring, idle, busy) is described in detail.
