摘要

这项工作提供了极性码和涡轮码应用于优化比奈奎斯特信号的比较。从接近香农极限的角度估计了这些编码技术和最优信号联合使用的效率。针对不同情况，计算了Shannon曲线与以谱值和能量效率为坐标的点之间的最小距离。使用极性编码可以更接近11%的香农极限。与“经典”BPSK信号相比，极性编码的最佳信号增益约为86%。

On The Joint Use of Optimal Faster Than Nyquist Signals with Polar and Turbo Codes

This work provides comparison of polar codes and turbo codes applicated to optimal Faster-than-Nyquist signals. The efficiency of the joint use of these coding techniques and optimal signals is estimated in terms of approaching the Shannon limit. For different cases, the minimum distance between the Shannon curve and the point which coordinates are the values of the spectral and energy efficiency is calculated. The use of polar codes allows to get closer to the Shannon limit of 11%. Compared to “classic” BPSK signals, optimal signals with polar coding come up with the gain about 86%.
