Iterative joint channel and data estimation for rank-deficient MIMO-OFDM

, 2007
In this paper we propose a turbo-detected multi-antenna-multi-carrier receiver scheme. Following the philosophy of the turbo processing, our turbo MIMO-OFDM receiver comprises a succession of detection modules, namely the channel estimator, the space ...

Design considerations and initial physical layer performance results for a space time coded OFDM 4G cellular network

, 2002
The exponential growth of cellular radio, WLANs and the Internet sets the context for a discussion on the role and objectives of 4G. In this paper OFDM is proposed as a leading candidate for a 4G cellular communications standard.
