Abstract
The downlink transmission in a single-cell wireless system is considered. The base station is equipped with an antenna array, and each user has one antenna. It is assumed that the channel state information at the base station is erroneous, with the exact channels lying in specified uncertainty regions. Linear spatial filters of all participants in the system are jointly optimized in order to minimize the total transmit power of the base station, while satisfying the users' predefined mean square error targets for all channels that comply with the adopted error models. The solutions are obtained using semidefinite programming methods from convex optimization theory.
