| Abstract | Over the past few decades, wireless communications and networking have experienced l.mprecedenred growth, \vith the advancements in video-coding technologies, transmitting real time encoded video programs over wireless net\vorks has become a promising service for such applications as video on demand and interactive video telephony. In most scenarios, multiple video programs are transmitted to multiple users simultaneously by sharing resource-limited wireless networks. In this thesis, we propose a system to transmit multiple 3-D embedded wavelet video programs over downlink multi-user OFDlvL We consider the fairness among users and fonllulate the problem as minimizing the users' maximal distortion subject to power, rate, and subcarrier constraints. By exploring frequency, time, and multiuser diversity in OFDM and flexibility of 3D embedded wavelet video codec, the proposed algorithm can achieve fair video qualities among all users. Compared to a scheme similar to the current multiuser OFDM standard (IEEE S02.11a), the proposed scheme outperforms 1-5 dB on the worst received PSNR among all users and has much smaller PSNR deviation. |
