【摘要】：为了进一步研究Han-Kobayashi(HK)传输策略在多用户Z高斯干扰信道上的性能,在中等弱干扰条件下构造了多用户Z高斯干扰信道可达速率内、外界.通过将信息分割为公有信息和私有信息,优化每个用户的公有信息和私有信息之间的比例,得出一条多用户Z高斯干扰信道速率RHK;通过增加级联Z高斯干扰信道的约束条件得出了一条小于RHK的速率Qg界;利用精灵辅助方案,得出了大于RHK的两条速率外界.通过计算速率内、外界之差得出:在中等干扰下,利用HK策略所得到的速率距离信道容量小于1 bit·s-1·Hz-1;在弱干扰下,随着总用户数量的增加,利用HK策略所得到的速率RHK与信道容量之间距离逐渐逼近1 bit·s-1·Hz-1.
[Abstract]:In order to further study the performance of Han-Kobayashi (HK) transmission strategy in multi-user Z Gao Si interference channel, we construct the reachable rate of multi-user Z Gao Si interference channel under the condition of medium weak interference. By dividing the information into public and private information, optimize the ratio between public and private information for each user, A multi-user Z Gao Si interference channel rate is obtained. By adding the constraint condition of concatenated Z Gao Si interference channel, a rate Q g bound less than RHK is obtained. By calculating the external difference within the rate, it is found that under medium interference, the rate distance channel capacity obtained by using HK strategy is less than 1 bit s-1 Hz-1, and under weak interference, with the increase of the total number of users, The distance between the rate RHK and the channel capacity obtained by using the HK strategy is gradually approaching 1 bit s-1 Hz-1.
