| 摘 要： | 对于一个给定的信道和一个特定的ldpc码族,针对由密度进化的不稳定性而造成的稳定中断事件,本文通过研究了BEC和AWGN信道中的稳定中断概率并确切表达了在块衰弱信道中的稳定中断概率,其仿真过程给出了在删除信道中容量逼近系统是怎样跳开了在块衰弱信道中的中断限制。

| Abstract: | For given channel instance and a fixed LDPC ensemble,Based on a stability outage which be cause by the density evolution,we formulate the stability outage probability for block fading channel by researching the SOP for the BEC channel and AWGN channel,Simulation results show that how the class of capacity-achieving ensembles on the erasure channel is bounded away from the outage limit on a block fading channel by studying of the SOP for AWGN channel and BEC channel. |

| Keywords: | LDPC codes stability condition outage probability block fading channels |
