  • 摘要: 為滿足日益增長(zhǎng)的高效通信和可靠感知需求,該文提出可重構(gòu)智能超表面(RIS)輔助無(wú)線攜能通信(SWIPT)-非正交多址接入(NOMA)系統(tǒng),該系統(tǒng)同時(shí)實(shí)現(xiàn)目標(biāo)感知和信息傳輸。考慮非完美連續(xù)干擾消除(SIC)和信道估計(jì)誤差(CEE)兩種非理想因素,分析了所提系統(tǒng)的可靠性、有效性以及雷達(dá)感知性能,分別推導(dǎo)出系統(tǒng)中斷概率(OP)、遍歷速率(ER)、檢測(cè)概率(PoD)以及雷達(dá)估計(jì)信息速率(REIR)的解析表達(dá)式。分析結(jié)果表明:非完美SIC和CEE對(duì)系統(tǒng)的性能有負(fù)面影響;中斷概率隨基站發(fā)射功率的增大而減小,在高信噪比區(qū)域趨于定值;遍歷速率及雷達(dá)估計(jì)信息速率隨基站發(fā)射功率增大而增加,在高信噪比區(qū)域穩(wěn)定于一個(gè)上限值;在不同的檢測(cè)閾值下,檢測(cè)概率隨基站發(fā)射功率的增大而增大;聯(lián)合雷達(dá)檢測(cè)和通信覆蓋概率(JRDCCP)分別隨中斷閾值和檢測(cè)閾值的升高而降低。
