Downlink SDMA for Hiperman Communications: The Obele Algorithm.

In the context of a fixed wireless downlink transmission, SDMA (spatial division multiple access) is a serious candidate to allow several users to communicate simultaneously. We study here a recently developed algorithm, first presented by Joel Bertrand in [Bertrand03]. The algorithm ensures a given QoS (quality of service) for all users in a multipath environment. We show that with a low number of iterations, a good QoS can be reached in an channel with up to 3 paths per user. This study was performed in the context of the IST-STRIKE project ([STRIKE])
