本論文考慮一個多使用者的正交分頻多工系統,使用者傳送影像資訊,同時受到其他用戶的干擾,並且試著重新分配功率與頻譜的資源。在本論文中,為了降低干擾進而提高資料傳輸率,提出資源分配結合干擾;干擾消除部份,我們利用回授領航訊號來估測干擾訊號之通道係數進而還原所傳送的訊號。模擬結果顯示,經本論文所結合的干擾消除機制與資源分配後,提升影像品質的同時亦可對抗外界之同頻干擾。
The cross layer resource allocation algorithm for OFDMA video transmission systems by Wang et. al. allocates the power and spectrum resources to the users according to both layer 1 channel state information and layer 5 rate distortion function. We propose to add multiple receive antennas for jamming resilience. We not only combine the existing jamming resilience technique, but we propose a novel resource allocation method by considering the angle between the jammer channel vector and the sender (desire signal) channel vector. The simulation results show that PSNR (video quality) increases by 10dB with the proposed resource allocation method.
