A Novel Modeling Method of Indoor Broadband Fixed Wireless Access MIMO Ricean Channel Based on Indoor Measurement at 4.9 Ghz

In this paper, we propose a novel modeling method of indoor broadband fixed wireless access (BFWA) MIMO Ricean channel based on empirical results obtained from stationary channel measurement at 4.9 GHz in both indoor line of sight (LOS) and non-LOS (NLOS) scenarios. The phenomena that K-factors decay versus delay linearly in both the LOS and NLOS scenarios are reported. Extended Saleh-Valenzuela cluster structure is proposed to model Ricean components and has been validated by empirical results. Channel model of IEEE 802.11n is employed as a baseline model and both ergodic and outage mutual information (I) are used as metrics to evaluate the performance of novel method. Simulation results show that, compared to the original way, the performance of novel method on ergodic I and outage I is closer to empirical results in respectively LOS and NLOS scenarios.
