Abstract :
The author presents a throughput analysis of slotted direct-sequence spread-spectrum multiple-access networks operating in the presence of background noise. The network consists of an infinite population of transceivers and the traffic is characterized by Poisson arrivals. The packets are protected by using forward-error correction coding along with hard decision decoding. The dependency of the optimal processing gain and code rate on system parameters is examined in detail. It is shown that, for a specified traffic intensity and signal-to-noise ratio, there is an optimal code rate and processing gain that maximizes the throughput. It is concluded that many important properties were revealed that are, quite likely, general characteristics of CDMA networks
