Downlink SDMA for HiperMAN Communications: The Obele Algorithm

Inhalt:
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 developped algorithm, first presented by Joël Bertrand. 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.
