Performance of Multiuser CDMA Receivers With Bursty Traffic and Delay Constraints
2012 (English)In: 2012 International Conference on Computing, Networking and Communications, ICNC'12, 2012, 428-433 p.Conference paper (Refereed)
In this work, we analyze the performance of linear multiuser CDMA receivers under bursty traffic and queuing delay constraints. An ON/OFF source is used to model the traffic burstiness and stochastic network calculus incorporates the queuing delay constraints in the analysis. At the physical layer, adaptive modulation and coding scheme is adopted and the channel service process is modeled by using a finite-state Markov chain. The following receivers are considered for performance evaluation: single-user matched filter, decorrelator, and linear minimum mean square error detector. We quantify the effect of these multiuser receivers on the traffic carrying capacity of uplink CDMA channels in the large system limit.
