Local common receiver-based protocols for spread spectrum data networks and performance analysis

Two protocols for spread spectrum data networks, the centralised controller (CC) and the local common receiver (LCR) protocols, are proposed and their performance is analysed. The network consists of N users, each of which is assigned with a unique receiver-based code. The users in network are divided into groups, each of which is assigned with a local common (LC) code. The analysis shows that both protocols offer a slightly worse performance than R, R-T and BCBS protocols when the traffic load is low. However, at a high traffic load, both the centralised controller and the LCR protocols give higher throughput and the lower delay than the previously reported protocols
