摘要 通过分析OFDMA-PON物理帧特性,提出了一个新的MAC层机制,包括物理层映射方案、子载波分配算法和轮询调度算法三个内容。并通过系统仿真验证了这一MAC层机制对于提升系统吞吐量的明显作用。 By analyzing the physical frame characteristics of OFDMA-PON, a new MAC mechanism which includes a physical mapping scheme, a dynamic sub-carriers allocation algorithm and a polling algorithm is propose. The system simulation results demonstrate that this new MAC mechanism can distinctly improve the performance of system throughput.
