摘要

在光子计数信道中，作者提出了一种并行速率可变的穿孔卷积编码PPM(脉冲位置调制)，以实现理想的误码率(BER)和传输带宽下的高能量信息效率。理论结果表明，对于某些码率组合，所提出系统的误码率性能、带宽扩展因子β和达到误码率=10/sup -6/所必需的能量信息效率。研究发现，在相同的带宽扩展系数下，在所有二进制擦除信道上具有相同码率的系统具有更好的误码率性能。研究还发现，根据信道条件选择合适的码率组合，所提出的系统可以获得所需的误码率和贝塔的高能量信息效率。此外，在较小的beta范围内，该系统比reed - solomon编码的PPM具有更好的误码率性能。

Parallel rate-variable coded PPM in photon counting channel

The authors propose parallel rate-variable punctured convolutional coded PPM (pulse position modulation) in a photon counting channel to achieve high energy information efficiency for desired bit error rate (BER) and transmission bandwidth. Theoretical results are shown for the BER performance, the bandwidth expansion factor beta , and a necessary energy information efficiency to achieve BER=10/sup -6/ of the proposed systems for some combinations of code rates. It is found that the system with the same code rates on all binary erasure channels has better BER performance than other systems for the same bandwidth expansion factor beta . It is also found that the proposed system can achieve high energy information efficiency for desired BER and beta by selecting a suitable combination of code rates depending on the channel conditions. Moreover, it is shown that the proposed system has better BER performance than Reed-Solomon-coded PPM in a small range of beta .<>
