Abstract
In this paper, we consider the use of multiple beams to simultaneously achieve both diversity and
multiplexing gain in multi-user domain in multiple access systems. Orthogonal multiple beams are generated
to provide the users with multiple channels at the same time, achieving multi-user diversity through each
channel. However, when the number of active users is not large, the performance can significantly be
affected by the interference from other users. To alleviate this problem, we propose a multi-beam scheme to
adjust the number of beams according to the channel condition or the number of users.
