Wideband MIMO channel capacity analysis based on indoor channel measurement

Based on the channel measurement in a typical indoor environment, wideband multi-input multi-output (MIMO) channel capacity analysis result is reported in this paper. A series of non line-of-sight (NLOS) and LOS measurement positions are planned for capacity comparison in different propagation conditions. For fixed received signal-to-noise ratio (SNR), slight average capacity loss in LOS cases is observed compared to NLOS cases. However, the capacity in presence of LOS component appears more position-sensitive than that in NLOS cases. When considering the large scale path loss difference introduced by the receiver movement, the capacity in LOS cases greatly exceeds the NLOS cases. A key finding is that the measured maximum channel eigenvalue fits t Location-Scale distribution rather than Gamma distribution in indoor scenario. Finally, Ricean K-factor and spatial correlation results are presented.
