  • 摘要: 傳統(tǒng)協(xié)作通信常采用譯碼轉(zhuǎn)發(fā)(DF)協(xié)議。而該協(xié)議在源-中繼節(jié)點(diǎn)鏈路通信質(zhì)量較差情況下,易出現(xiàn)誤碼傳播現(xiàn)象。為了改進(jìn)該問(wèn)題,該文提出可應(yīng)用于編碼協(xié)作(CC)機(jī)制的Raptor編碼協(xié)作方案,其可在高信噪比下獲得較大編碼增益和滿(mǎn)分集增益。它在源節(jié)點(diǎn)和中繼節(jié)點(diǎn)使用不同Raptor編碼,使中繼節(jié)點(diǎn)新編碼碼字為源節(jié)點(diǎn)碼字的部分校驗(yàn)信息,使接收端所得碼字獨(dú)立不等。因此,目的節(jié)點(diǎn)在分別接收來(lái)自不同獨(dú)立鏈路消息后,可根據(jù)碼字間固有關(guān)系聯(lián)合譯碼,以獲得額外發(fā)送空間分集增益。為了降低復(fù)雜度,Raptor碼的預(yù)編碼還可采用整數(shù)序列構(gòu)造的準(zhǔn)循環(huán)低密度奇偶校驗(yàn)(QC-LDPC)碼,從而獲得較低線性預(yù)編碼復(fù)雜度。仿真表明:在誤比特率(BER)為10-4 時(shí),所提Raptor編碼協(xié)作方案較傳統(tǒng)DF協(xié)議Raptor方案,Raptor與分布式空時(shí)分組碼(DSTBC)結(jié)合方案,分別有2 dB和1 dB增益。此外,當(dāng)中斷概率為10-2時(shí),其性能較CC, DF協(xié)作方案提高了約2 dB和7 dB。
