【摘要】：為了進(jìn)一步研究Han-Kobayashi(HK)傳輸策略在多用戶Z高斯干擾信道上的性能,在中等弱干擾條件下構(gòu)造了多用戶Z高斯干擾信道可達(dá)速率內(nèi)、外界.通過將信息分割為公有信息和私有信息,優(yōu)化每個用戶的公有信息和私有信息之間的比例,得出一條多用戶Z高斯干擾信道速率RHK;通過增加級聯(lián)Z高斯干擾信道的約束條件得出了一條小于RHK的速率Qg界;利用精靈輔助方案,得出了大于RHK的兩條速率外界.通過計算速率內(nèi)、外界之差得出:在中等干擾下,利用HK策略所得到的速率距離信道容量小于1 bit·s-1·Hz-1;在弱干擾下,隨著總用戶數(shù)量的增加,利用HK策略所得到的速率RHK與信道容量之間距離逐漸逼近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.
