Chapter 4.3 4.3 N denotes the power of the white noise impairing the received signal. Already from (4.3.1) it should be clear that the two fundamental factors limiting the achievable data rate are the available received signal power, or more High data rates in mobile communications Erik Dahlman, Stefan Parkvall, Johan Skold and Per Beming As discussed in Chapter 4.2, one main target for the evolution of 3G mobile communication is to provide the possibility for significantly higher end-user data rates compared to what is achievable with, for example, the first releases of the 3G standards. This includes the
