摘要：
This paper reports the development of a configurable, non-realtime, 2x2 multi-antenna testbed operating at 5.25GHz with a bandwidth of 25MHz. MIMO-OFDM modulation and demodulation are performed offline. The unit is fully calibrated and was used in extensive indoor wireless measurements at UCLA. The paper reports measurements for SISO, SIMO1x2 and MIMO2x2 setups in line of sight and non line of sight channels. These measurements show that LOS channels are not necessarily detrimental for MIMO performance. Further experiments show that with -3dBm of transmit power uncoded data rates of 140Mbps are achievable.
