| 摘 要： | 为了能有效地逼近高斯干扰信道的容量边界,提出了一种分布式率分裂的方案.以二用户高斯干扰信道为例,该分布式率分裂方法能建模成一个非协作博弈论模型,并且提出一种迭代多水平面功率注水算法,能达到该博弈模型的纳什均衡,同时给出了迭代收敛的一个充分条件.计算机仿真表明,通过分布式率分裂方案以及迭代多水平面功率注水算法而获得的高斯...

| Abstract: | A distributed rate-splitting (DRS) scheme is proposed to approach the rate region boundary of the two-user Gaussian interference channel. It is shown that the DRS scheme can be formulated as a non-cooperative game. Therefore, an iterative multiple waterlevels water-filling algorithm (IML-WFA) is developed to efficiently reach the Nash equilibrium (NE) of the non-cooperative game and a sufficient condition on the convergence of IML-WFA is proposed. Numerical examples show that the rate-tuples achieved by the DRS are very close to the boundary of the well-known HK regions. |
