2006
IEEE International Workshop on Quality of Service, IWQoS
Preserved Fulltext
We present numerical results on the various trade-offs between these measures that provide insight into the behavior of OFDM based cellular systems and help dimension the parameters of a reuse partitioned ...
The current 3GPP working assumption on the Evolved Universal Terrestrial Radio Access (E-UTRA) physical layer is that it will be based on single carrier frequency division multiple access (SC-FDMA) for ...
Finally, based on the numerical results, in Section V we discuss the pros and cons of interference mitigation techniques for E-UTRA.
