Adaptive Antenna Array Assisted Dynamic Channel Allocation Techniques
Adaptive Antenna Array Assisted Dynamic Channel Allocation Techniques
Abstract—The performance of base station adaptive antenna arrays (AAAs) is investigated in conjunction with fixed channel allocation (FCA) and dynamic channel allocation (DCA) schemes. Locally distributed DCAarrangements are studied and benchmarked against standard FCA, in the context of both line-of-sight (LOS) and multipath propagation environments. One-, two-, four-, and eight-element AAAs are employed using the sample matrix inversion (SMI) beamforming algorithm, in both the up- and the down-link. In most investigated scenarios, the locally optimized least interference algorithm (LOLIA) exhibited the best overall compromise in terms of a set of combined metrics, such as the forced termination probability, new call blocking probability, and the probability of a low quality access. Index Terms—Adaptive antennas, adaptive array, beamforming, dynamic channel allocation (DCA), network capacity, wireless networks.
