基于OFDMA-PON的选择性节能接收模式

摘要

In order to solve the problem of traditional OFDMA-PON at downlink direction,the ONU receivers have to receive and process all signals which are sent by OLT,this paper proposes three selective receiving modes based on time domain,and verifies the proposed selective receiving modes can effectively save the power consumption of OFDMA-PON system through simulation.%针对传统光正交频分复用接入无源光网络(OFDMA-PON)在下行方向上,ONU接收机对OLT发送的广播信号全部进行接收处理这一现象,提出了3种不同的基于时域的选择性接收模式,并通过仿真验证出3种选择性接收模式确实可以有效节约OFDMA-PON系统的能耗.
