Delay Analysis and Comparison of OFDM-TDMA and OFDMA Under IEEE 802.16 QoS Framework

Date: January 2008
Type: White Paper
Rating: (0)

Overview: This research paper discusses the delay analysis and comparison of OFDM-TDMA and OFDMA using a flow control scheme under the QoS framework of IEEE 802.16. The paper investigates the maximum packet delay performance by deriving delay bounds for several multiaccess modes with different subcarrier/time-slot assignment and bit allocation schemes. The analytical delay bounds provide insights into the performance difference among different multiaccess schemes, and demonstrate each scheme’s capability of supporting real-time, delay-sensitive multimedia applications.
