... detailed performance evaluation of any networking protocol. Performance evaluation results for some ad hoc network protocols were previously reported [1, 14], which primar- ily covered the impact of ... and TORA. Additional ad hoc network protocols, such as DSDV and ZRP, could be added in OPNET for com- prehensive performance evaluation. REFERENCES [1] E. Celebi, P...

... wireless communications systems. An important advantage of using STF- domain spreading in MIMO OFDM–CDMA is that the maximum number of users supported 11 D. Performance Evaluation for Zero Forcing Receiver In ... spreading on all the signal domains provides extra flexibility in user multiplexing and scheduling. In addition, it offers better diversity/multiplexing trade-off. The perf...

... multiplexing and schedul- ing. In addition, it offers better diversity/multiplexing trade-off. The performance of MIMO OFDM-CDMA scheme using STF-domain spreading is investigated with zero-forcing ... without degrading overall system performance, and therefore it is less complex. In other OFDM-CDMA systems, RAKE receiver is widely used to take advantage of the entire frequency spread...
