Abstract:

In this paper, we derive the end-to-end error probability of multi-hop networks employing CDMA transmission in a multiuser environment. The standard Gaussian approximation (SGA) is used to model the multiple access interference (MAI) in the system. We consider multihop networks employing serial, parallel and selection relaying using decode-and-forward (DF) technique. Additionally, we investigate the effect of different system parameters on the error performance of the system, such as the number of users and the path loss exponent. Results show that as the number of users increases, the improvement coming from the relaying decreases. However, relaying still gives significant improvement, especially in parallel relaying.
