Ultra Wideband (UWB) Transceiver Design Using Channel Phase Precoding (CPP)
A novel transceiver design for ultra wideband (UWB) communication systems using the channel phase precoding (CPP) technique is proposed in this work. With the CPP-UWB transceiver, we encode data symbols using the reversed order of the channel phase. A simple phase estimation algorithm is presented for the CPP-UWB implementation. Owing to its ability to coherently combine the channel magnitude o...
متن کاملTransceiver design using linear precoding in a multiuser multiple-input multiple-output system with limited feedback
The authors investigate quantisation and feedback of channel state information in a multiuser (MU) multiple-input multiple-output (MIMO) system. Each user may receive multiple data streams. The authors design minimises the sum mean squared error (SMSE) while accounting for the imperfections in channel state information (CSI) at the transmitter. This study makes three contributions: first, the a...
متن کاملRobust Transceiver Design for Multiuser MIMO Downlink with Channel Uncertainties
This letter addresses the problem of robust transceiver design for the multiuser multiple-input-multiple-output (MIMO) downlink where the channel state information at the base station (BS) is imperfect. A stochastic approach which minimizes the expectation of the total mean square error (MSE) of the downlink conditioned on the channel estimates under a total transmit power constraint is adopted...
متن کاملA Channel Model for Ultrawideband Indoor Communication
This paper describes the wireless channel model that the IEEE 802.15.3a standardization group has developed for the evaluation of ultrawideband communications systems. We discuss the measurements that form the basis of this model. These measurements establish important differences between UWB channels and narrowband wireless channels, especially with respect to fading statistics and time-of-arr...
متن کاملProbabilistic Constraint Robust Transceiver Design for MIMO Interference Channel Networks
—In this paper, we investigate the robust transceiver design for Multi-Input Multi-Output (MIMO) Interference Channel (IC) networks with imperfect Channel State Information (CSI). With the assumption of Gaussian CSI uncertainty, a probabilistic constraint robust transceiver design problem is formulated by maximizing the average received signal while constraining the probability of large interf...
