This paper presents analysis results relative to an underground MIMO channel. Measurement campaigns were conducted in a former gold mine at a center frequency of 5.8GHz under Line- Of-Sight (LOS) scenario. Extracted data have been processed to obtain the relevant statistical parameters of the channel. The resulting propagation behavior difiers from frequently encountered in more typical indoor environments, such as o-ces and corridors. Indeed, the path loss exponent is less than 2 in MIMO conflguration due to the large number of scatters that increase the received power when compared to the free-space case. Moreover, there has been a signiflcant increase in spectral e-ciency, when using MIMO technique. Hence, according to calculated statistical parameters, wireless link performance is improved through the use of the MIMO scheme. All in all, multi antenna systems present an ideal alternative for future underground communication systems.
