In this paper, we use a 4times4 MIMO testbed to investigate the experimental performance of the blind channel estimation technique presented in (Shahbazpanahi et al., 2005). The operating frequency throughout all experiments was selected to be 2.47 GHz and the transmission bandwidth was 20 MHz. Our experimental results show that the performance of the blind technique can be very close to that of non-blind training based receiver which uses a significant bandwidth overhead as compared to the blind approach developed in (Shahbazpanahi et al., 2005).
