Optimum Number of Beams in Multiuser Opportunistic Schemes under Qos Constraints

  title={Optimum Number of Beams in Multiuser Opportunistic Schemes under Qos Constraints},
  author={Nizar Zorba},
Scheduling in a Broadcast (BC) channel based on partial Channel State Information at the Transmitter (CSIT) is carried out through an opportunistic random beamforming technique. Within a more practical perspective, this paper first presents a transmission strategy where a minimum rate per user is required. This minimum rate is demanded by each scheduled user to properly decode and manage its received signal, which stands as a possible Quality of Service (QoS) indicator for the system behaviour… CONTINUE READING
