【摘要】：通过研究功率分配对空间耦合数据传输的性能影响,在空间耦合数据流间干扰完全消除的情况下,利用密度进化与势能函数证明了等功率传输性能最优.为了以较少的性能损失为代价,减少等功率传输引起的高检测复杂度,提出了一种功率分配算法实现非等功率传输.外信息转换图分析和仿真结果证实了理论分析的正确性和所提算法的可行性.
[Abstract]:By studying the effect of power allocation on the performance of spatially coupled data transmission, the optimal performance of equal-power transmission is proved by density evolution and potential energy function under the condition of complete elimination of interference between spatially coupled data streams. In order to reduce the high detection complexity caused by equal power transmission at the cost of less performance loss, a power allocation algorithm is proposed to realize unequal power transmission. The correctness of the theoretical analysis and the feasibility of the proposed algorithm are verified by the analysis of the external information conversion diagram and the simulation results.
