The statistics of ICI and the performance enhancement possibility have been proven by practical
implementation of a system which uses FQAM.
FQAM system environment for cellular downlink OFDMA networks is shown in Figure 23 and 24.
Our experimental results show that the transmission rates for interference-limited users in FQAM-based
OFDMA networks are around 300% higher than those in QAM-based OFDMA networks [23][24].
