abstract = "A new MAC frame length design for maximizing the saturation throughput of the PCA scheme in the WiMedia Multiband-OFDM UWB systems is presented in this paper. The proposed design is carried out by extending the original EDCA model of the IEEE 802.11e into the Multiband-OFDM UWB protocol. The extended model considers the effects of the BER, the transmission opportunity limits and the uniqueness of WiMedia MAC timing structure. The station throughput is maximized when the length of the transmitted frame is set to an optimal value, and this optimal frame length increases exponentially when the value of the SNR is high. The optimal frame length is independent of the number of the active stations, data rate and the priority of the access categories. Therefore, a station can dynamically adapt the frame length according to the current SNR level so as to maximize its saturation throughput in the Multiband-OFDM UWB systems.",
