  • 摘要: 針對能量受限的合作認(rèn)知網(wǎng)絡(luò),該文研究在保證主用戶服務(wù)質(zhì)量要求下,認(rèn)知用戶能量效率最大化問題。認(rèn)知用戶利用信能同傳技術(shù)接收主用戶信號,并采用解碼轉(zhuǎn)發(fā)協(xié)議協(xié)助主用戶通信?;诜质揭?guī)劃和引入輔助變量將原始非凸問題轉(zhuǎn)換為凸優(yōu)化問題進(jìn)行求解,并提出一種迭代的資源分配算法。仿真結(jié)果表明,所提算法能夠快速收斂于最優(yōu)解。與能量合作方案相比,該文所采用方案能量效率顯著提高,同時能更好地保證主用戶服務(wù)質(zhì)量要求。
