Abstract
This paper aims at the eigenvalue analysis and its modeling for 2x2 (i.e., 2 transmit and 2 receive antennas) Multiple Input Multiple Output (MIMO) channel capacity based on Non Line-Of-Sight (NLOS) wideband indoor measurements. Our channel sounding system is the portable Band Exploration and Channel Sounding (pBECS) System, which works at a carrier frequency of 2.58GHz with 20MHz bandwidth. From the measured data, we investigate Transmit Antenna Correlation Coefficient (TxACC), Receive Antenna Correlation Coefficient (RxACC), channel capacity and eigenvalues of HH* where H and (*) are channel frequency response matrix and conjugate transpose. Based on the eigenvalue characteristics, we derive mean and variance of eigenvalues which are a function of the absolute values of TxACC and RxACC, |TxACC| and |RxACC|, and then model the eigenvalues for 2x2 MIMO channel capacity. Monte Carlo simulations are used to generate the eigenvalue realizations according to the model. The results are compared with the measured data and good agreements are found. ©2009 IEEE.
