The future wireless systems are anticipated to support much higher data rates than what the existing systems can currently offer. It has been universally agreed that a richer set of QoS levels are still needed for the emerging networks to successfully launch the upcoming applications. This is because the QoS components reflect the networks availability and transmission quality. Therefore,spectrally efficient techniques, which could simultaneously meet the QoS guarantees is highly essential. This prompted for developing QoS solutions through radio adaptation techniques, that are suitable to...
