On the Channel Sounding Technique Using MIMO Software Radio Architecture
Advantages and issues of the channel sounding technique using MIMO software radio architecture are discussed. By end of February, the first prototype consisting one transmitter unit and one receiver unit will be available. Both have four RF ports respectively. Before the over-the-air test utilizing dual-polarized antennas, baseband, RF and array antenna calibrations will be required. By the year of 2012, 24 ? 24 MIMO software radio testbed is planned to be ready, and the field measurements in microcell and picocell are planned.
