Abstract
The IMT-A geometry-based stochastic modeling (GBSM) channel model provides an accuracy and flexibility method for wireless channels evaluations in the telecommunication standards. However, it is a problem for practical engineering application considering the high calculation complexity of IMT-A GBSM channel models. To satisfy requirements from practical engineering applications, we proposed an improved IMT-A GBSM channel model for Urban micro-cellular scenarios. The improved IMT-A GBSM channel model is traded off by the calculation complexity and accuracy. Performance analysis results indicate that the calculation complexity of improved IMT-A GBSM channel model has been obviously reduced and correlation metrics of the improved IMT-A GBSM channel model still kept consistency with the traditional IMT-A GBSM channel model. Therefore, the improved IMT-A GBSM can be used for practical telecommunication engineering applications in UMi scenarios.
