摘　　要：We provide a broad look at the field of limited feedback in wireless communication.We review works of limited feedback with various combinations of single antenna,multiple antenna,single-user and multiuser technology and provide a synopsis of the role of limited feedback in wireless communication systems.We also study how the feedback rate can be minimized without losing the gains due to adaptive transmission and multiuser diversity.It seems that the best possible feedback scheme is not invented yet.As another conclusion is that there are still many issues to study before the scheme can be used in practice.We provide a broad look at the field of limited feedback in wireless communication.

We also study how the feedback rate can be minimized without losing the gains due to adaptive transmission and muhiuser diversity. It seems that the best possible feedback scheme is not invented yet. As another conclusion is that there are still many issues to study before the scheme can be used in practice.
