Interference between femto-cell systems is a critical factor for the deployment of such systems in, e.g., residential areas. In this paper we report on a residential channel measurement campaign focusing on the channel properties for femto-cell systems. We characterize basic channel properties such as delay spread and interference levels between different furnished residential houses. In addition...
This paper considers fundamental limits on adaptive multiple-input multiple-output (MIMO) transmission with imperfect channel state information at the transmitter (CSIT). First, the achievable ergodic rates are derived for both single-user and multi-user MIMO systems with different CSIT assumptions, which shows that single-user MIMO is robust to imperfect CSIT while multiuser MIMO loses spatial multiplexing...
