On the OFDMA FDD mode in 3G-LTE (original) (raw)
New generations of cellular radio systems are currently being developed based on OFDM transmission with OFDMA as the multiple access scheme. The demand for high data rates in reasonably large areas is omnipresent, but the conventional cellular architecture offers does not only a maximum rate depending on the distance. Close to the base station, the higher received SIN R valueallows the highest Modulation&Coding scheme (PhyMode), which offers the highest data rate. In this paper we user the mutual information approach to calculate the maximum data rate based on the SIN R at all positions in an interference-limited radio cell.
