Abstract

In this paper, frequency characterization of a UWB indoor MIMO channel is presented. Measurements were conducted on a 4×4 MIMO channel within the frequency range of 2 to 5 GHz with a fixed SNR of 30dB. The impact of antenna polarization on the mutual information was also analyzed with antennas interelement spacing fixed at 2λ. Channel capacity was analyzed both in NLOS and LOS scenarios. It is realized that the spectral efficiency of the channel is a function of the operating frequency and the channel bandwidth.
