PERFORMANCE ANALYSIS OF A SLOTTED CODE DIVISION MULTIPLE ACCESS (CDMA) NETWORK.

A performance model of a multihop code-division multiple access (CDMA) spread-spectrum network is presented. Time is divided into slots, and the network nodes are synchronized such that fixed-length messages will only be sent at the beginning of slots. The message-generation processes at the nodes are assumed to be independent Bernoulli processes. A node may transmit or received in a slot, but not both. Each transmission is preceded by a preamble used by the receiver for acquisition purposes. Both the preamble and the message are encoded in the PN code which is unique to the particular receiver. Steady state results for the throughput versus offered traffic, and the delay versus throughput were obtained. This model will be illustrated by examples.link_to_subscribed_fulltex
