Cross-layer QoS Analysis of Opportunistic OFDM-TDMA and OFDMA Networks

Yu-jung Chang, Feng-tsun Chien, C.-C.J. Kuo
2007 IEEE Journal on Selected Areas in Communications  
It is demonstrated by analysis and simulation that OFDMA outperforms OFDM-TDMA in QoS metrics of interest. Thus, OFDMA has higher potential than OFDM-TDMA in supporting multimedia services.  ...  With the M/G/1 queueing model and flow control results, our analysis provides important insights into the performance difference of these two multiaccess systems.  ...  Specifically, packets are classified into the premium and the best-effort two classes and better service is granted to the premium class.  ...

Erlang Capacity of Multi-Class TDMA Systems with Adaptive Modulation and Coding

H. Wang, V. B. Iversen
2008 2008 IEEE International Conference on Communications  
Erlang capacity is traditionally defined as the maximum value of offered traffic among different service classes that the system can support when the blocking probabilities at the call admission control  ...  In this paper, we evaluate the Erlang capacity of a TDMA system with AMC supporting voice and data traffics, by taking both the blocking and the outage probabilities into account.  ...  Two types of services, voice service and data service, are supported by the system. Voice service is not tolerant to packet delay, thus requires a constant bit rate.  ...
