论文摘要
在本文中，我们阐明了运输层中自适应，有效的错误编码如何有助于确保应用程序要求。我们回顾了MDS代码的使用，并表明二元编码可以显着降低复杂性，从而提高嵌入式设备的适用性。我们利用了极地代码中发生器矩阵的刻度对称结构，以建立对通道（极化效应）和数据包（多播传输所需的通用性）的色散双重性，从而构建了逐步冗余的系统极性代码，尽管其性能较低，但它还是与MDS相近的中等范围损失速率附近的代码。
In this paper, we shed light on how an adaptive, efficient error coding in the transport layer helps ensure the application requirements. We recap the use of MDS codes and show that binary coding can significantly reduce the complexity and hence increase the applicability also for embedded devices. We exploit the persymmetric structure of the generator matrix in polar codes to establish a duality of dispersion over channels (the polarization effect) and over packets (the generality required for multicast transmission), thereby constructing systematic polar codes for incremental redundancy whose performance, despite a much lower complexity, is near to MDS codes for medium-range residual loss rates.
