At lower frequency bands, TR in conjunction with array antennas at transmit (Tx) or Rx has been shown to significantly improve its focusing performance relative to the case of single antennas at both link ends. This work for the first time investigates TR processing for multi-antenna systems in the 60GHz band. We consider both multiple-input-single-output and single-input-multiple-output (SIMO) channels measured in the 60GHz band in a conference room environment and investigate the effect of array size and its orientation on spatial and temporal compression properties of TR. It is observed that the root mean square (RMS) delay spread can be reduced significantly by the application of TR in the 60GHz band and that the orientation of the Rx array significantly affects TR performance for SIMO systems.
