“…Given that GBTB was shown, from all of our results, to be the second best policing mechanism for conforming users, we proceeded to make one more comparison between FSA-TB and GBTB. We have found, via simulation, the required token generation rate for which each mechanism achieves 1% ( [21]) and 0.01% ( [22]) of marked traffic, i.e., very good and excellent video QoS, respectively. These rates are presented in Table VIII for each trace used in our study.…”

“…Although the dynamic resource allocation schemes proposed for OFDMA/SDMA systems in [1,9,11,13,17,18] achieved the suboptimal solutions of their corresponding optimization problems, all of them were designed for single receive antenna terminals. When each terminal is equipped with multiple antennas, however, the optimization problem becomes much more complicated since the signal space of each user has multiple dimensions.…”

“…The MIMO OFDM systems can multiplex users both in the frequency and the spatial domains. A resource allocation algorithm is proposed for orthogonal frequency division multiple access combined with space division multiple access (OFDMA/SDMA) systems for downlink where orthogonality in the spatial domain among users can be assumed [3]. However, due to imperfect orthogonality in the spatial domain on uplink, the co-channel interference caused by the subcarrier reuse may lower the system's performance.…”
