中文摘要：
通过分析Han．Kobayashi（HK）策略在Ⅳ用户对称循环高斯干扰信道中的应用，提出了一种自适应奇偶对称速率分裂方案。该方案针对不同的信道条件设计出相应的速率分裂方案及最优分裂系数，在简化了计算复杂度的同时，使系统和速率趋近HK和速率内界。最后，分别在高信噪比和一般信噪比环境下进行仿真发现，自适应奇偶对称速率分裂方案的和速率在很大范围内明显大于对称速率分裂方案和Tse等人提出的速率分裂方案的和速率，且在一般信噪比下能够逼近HK和速率内界。
英文摘要：
By analyzing the performance of Han-Kobayashi （HK） strategy in the N-user cyclic Gaussian symmetric in- terference channel, an adaptive odd-even symmetric rate-splitting scheme was proposed to reduce the complexity and in- crease the sum-rate to the inner bound of HK, which contains various schemes based on rate-splitting and optimal split ratio. Numerical simulation results of symmetric scheme in the high SNR and the general SNR regimes indicate that, in wide range of transmitted power and interference factor, the sum-rate achieved using adaptive rate-splitting scheme is higher than that achieved using the scheme proposed by Tse et al., and approaches the inner bound of HK scheme in the general SNR regimes.
