COMPARISON OF DOUBLE-DIRECTIONAL CHANNEL RESPONSE AT 2.4 AND 5.2 GHZ FROM INDOOR CO-LOCATED WIDEBAND MIMO CHANNEL MEASUREMENTS

Since initial research in multiple-input multiple-output (MIMO) wireless systems [1], the opportunities and demands of higher spectral efficiency, quality of service and data rates in wireless systems have stimulated ongoing research in this area. MIMO architectures are potentially good candidates for future wireless systems, since they employ multiple antennas at both the transmitter (TX) and the receiver (RX) to significantly increase channel capacity in a multi-path environment, without increasing the system bandwidth or transmit power.
