To establish a wide service area of multiuser (MU) MIMO distributed antenna system (DAS), the use of dynamic clustering scheme (CS) is necessary to reduce a huge amount of computation in precoding which is widely applied in MU-MIMO communication systems. 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 by observing the cumulative distribution function and expectation of the system sum rate. We also compare the characteristics of our proposed CS 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 universality, 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 our proposed CS provides better performance than the existing schemes in the literature and can achieve similar sum rate as the exhaustive search. |
