description: This paper presents an improved test-bed designed  for analyzing the spatial behaviour of wideband indoor channels  using MIMO-OFDM systems. A 3D antenna positioning system  (3-DAPS) is specifically designed for obtaining 3D spatial data.  Also, it allows carrying out some measurements in the range of  correlation distance where fading of the radio channel link is  significant for indoor scenarios. Special emphasize is made on the  RF calibration module, which is designed to track the frequency  response of all RF chain of transmitter and receiver and apply  those responses to the channel measurements. The average of the  pseudo-spectrum MUSIC over all frequencies improves the  resolution of the spatial spectrum giving clear peaks where a  signal source is and smoothing fake peaks coming from scatters.
