Abstract :
This contribution studies the impact of adaptive modulation (AQAM) on network performance, when applied to a cellular network using adaptive antennas with fixed channel allocation (FCA) and locally distributed dynamic channel allocation (DCA) schemes. The performance advantages of using adaptive modulation are quantified in terms of overall network performance, mean transmitted power and the average network throughput. With the advent of AQAM 33% and 87% increases in the number of users can be supported by FCA and DCA, respectively
