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.
一种改进的IMT-A GBSM MIMO信道模型
IMT-A基于几何的随机建模(GBSM)信道模型为电信标准中的无线信道评估提供了一种精确和灵活的方法。但IMT-A GBSM信道模型的计算复杂度较高,在实际工程应用中存在问题。为满足实际工程应用的需要,提出了一种改进的IMT-A GBSM信道模型。改进的IMT-A GBSM信道模型在计算复杂度和精度上有所折衷。性能分析结果表明,改进后的IMT-A GBSM信道模型计算复杂度明显降低,相关指标与传统IMT-A GBSM信道模型保持一致。因此,改进后的IMT-A GBSM可用于UMi场景下的实际通信工程应用。
