Dynamic Channel Allocation Techniques Using Adaptive Modulation and Adaptive Antennas
Blogh, J.S., Cherriman, P.J. and Hanzo, L. (2001) Dynamic Channel Allocation Techniques Using Adaptive Modulation and Adaptive Antennas. IEEE Journal on Selected Areas in Communications, 19, (2), 312-321.
This contribution studies the impact of adaptive quadrature amplitude modulation (AQAM) on network performance when applied to a cellular network, using adaptive antennas in conjunction with both fixed channel allocation (FCA) and locally distributed dynamic channel allocation (DCA) schemes. The performance advantages of using adaptive modulation are investigated in terms of the overall network performance, mean transmitted power, and the average network throughput. Adaptive modulation allowed an extra 51% of users to be supported by an FCA 4-QAM network, while in conjunction with DCA, an additional 54% user capacity was attained. Index Terms—Adaptive antennas, adaptive modulation, adaptive arrays, beam-steering, DCA, dynamic channel allocation.
