In multiuser MIMO systems, the base station schedules transmissions to a group of users simultaneously. Since the data transmitted to each user are different, in order to avoid the inter-user interference, a transmit preprocessing technique which decomposes the multiuser MIMO downlink channel into multiple parallel independent single-user MIMO channels can be used. When the number of users is larger...
We propose a practical SVD-based scheduling technique for MIMO broadcast channel. Multiuser diversity is exploited by scheduling transmissions simultaneously to a group of users who have the best instantaneous channel quality. In order to avoid the inter-user interference, we use a transmit preprocessing technique which decomposes the multiuser MIMO downlink channel into multiple parallel independent...
