Abstract
Broad-band wireless communication systems can effectively utilize transmitter precoding to compensate severe channel distortions based on forward link channel estimate. We demonstrate the integration of precoded transmission into a duplex channel estimation mechanism using bent-pipe signal feedback. We also present an effective fractionally spaced precoder design based on the base station transmitter estimation of the downlink channel. We focus on feedback of fractionally spaced samples and demonstrate the significant improvement when the channel estimator is given access to the precoder and filters used by the wireless transmitters.
