To establish a wide service area of a multiuser multiple-input multiple-output (MU-MIMO) distributed antenna system (DAS), the use of dynamic clustering scheme (CS) is necessary to reduce a huge amount of computation in precoding. In this study, we propose a novel and efficient algorithm for dynamic clustering by employing a orthogonal frequency division multiplexing based MU-MIMO DAS and investigate its performance. We also compare the characteristics of the proposed and other classical dynamic CSs, for instance, exhaustive search, norm-based and location-based adaptive algorithm, in terms of sum rate improvement. Moreover, in order to make our results more universal, we further introduce the spatial correlation in the considered system, in particular, the spatial correlation in shadowing that exists widely in DASs. Computer simulation results indicate that the proposed CS provides better performance than the existing schemes and can achieve similar sum rate as the exhaustive search. |
