  • 摘要: 該文針對多用戶全雙工中繼干擾信道,同時(shí)考慮全雙工中繼自干擾消除及用戶端干擾消除問題。首先,提出了基于最大化全局互信息量的自干擾消除和干擾對齊算法,并具體給出了自干擾消除矩陣的具體求解算法和方案。進(jìn)一步,給出了信號(hào)對齊和干擾抑制的可行性條件,并分析了系統(tǒng)的互信息量和所受干擾噪聲功率,以及系統(tǒng)的自由度。理論分析和仿真結(jié)果顯示,與現(xiàn)有的典型全雙工中繼方案相比,該文算法可以提高系統(tǒng)互信息量和自由度,并有較低誤碼率;另外,該文算法的中繼只需進(jìn)行簡單的功率約束,不需做復(fù)雜的信號(hào)處理,降低了整個(gè)系統(tǒng)的信號(hào)處理復(fù)雜度。
