A Downlink SS-OFDM-F/TA Packet Data System Employing Multi-User Diversity

  • R. Novak
  • W. A. Krzymien


A spread spectrum orthogonal frequency division multiplexing (SS-OFDM) option for the downlink of a high data rate packet based system is proposed and discussed in this paper. Frequency and time division multiplexing techniques are used to allocate resources for packet transmission. Adaptive modulation, proportionally fair scheduling, and hybrid ARQ are used to increase throughput and reduce delay. Cell throughput results are presented.
