On transmit diversity with imperfect channel state information
IEEE International Conference on Acoustics Speech and Signal Processing, 2002The optimal transmission strategy of a multiple-input single-output wireless communication link is studied in which the receiver has full channel state information and the transmitter has only long-term channel state information in terms of the channel covariance matrix.

Feedback of Channel State Information in Wireless Systems
2007 IEEE International Conference on Communications, 2007The problem of sending channel state information from the receiver to the transmitter of a wireless link is investigated in this paper. If the channel state is Gaussian distributed, this problem is equivalent to that of transmission of a Gaussian source over a noisy channel.

On decoding equations with partial channel state information
2010 44th Annual Conference on Information Sciences and Systems (CISS), 2010We have shown that over interfering links, it is possible to decode a function of the involved messages much more efficiently than the full messages themselves. This is useful for example as a physical layer for network coding. Typically, some degree of channel state information at the receiver is required.

On multiple user channels with state information at the transmitters
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005We extend Shannon's result on the capacity of channels with state information to multiple user channels. More specifically, we characterize the capacity (region) of degraded broadcast channels and physically degraded relay channels where the channel state information is causally available at the transmitters.

Cooperative Relaying with Imperfect Channel State Information
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008We consider relay cooperation with imperfect channel state information (CSI) in the downlink of wireless networks. In particular, we consider a two-phase transmission where in the first phase the base station broadcasts information to the relays; the relays decode the data fully or partially depending on the transmission rate and the quality of their ...

Imperfect channel-state information in MIMO transmission
IEEE Transactions on Communications, 2006A especially favorable multiple-input multiple-output (MIMO)-based concept for future mobile radio systems consists of the application of joint detection (JD) in the uplink and joint transmission (JT) in the downlink. By this, all the computational complex signal processing is shifted to the base station (BS), resulting in low-complexity mobile ...
