  • 摘要: 由于卷積碼序列的0,1 bit的概率幾乎均衡,對(duì)于卷積碼自同步加擾的擾碼盲識(shí)別,現(xiàn)有的基于輸入序列0, 1 bit概率不均衡性的識(shí)別方法均已失效,為此該文提出一種新的自同步擾碼盲識(shí)別方法。首先將卷積碼自同步加擾序列進(jìn)行分塊處理,通過加擾數(shù)據(jù)塊與卷積碼校驗(yàn)向量相乘產(chǎn)生新的序列;然后以最大化新生成序列間線性約束關(guān)系成立概率為準(zhǔn)則,利用解調(diào)輸出的軟判決序列建立自同步擾碼反饋多項(xiàng)式系數(shù)的代價(jià)函數(shù);最后根據(jù)自同步擾碼反饋多項(xiàng)式的項(xiàng)數(shù)特點(diǎn),在求解代價(jià)函數(shù)時(shí)改進(jìn)了動(dòng)態(tài)搜索煙花算法,增加了對(duì)煙花個(gè)體元素值的約束操作,由求解出的參量值識(shí)別出自同步擾碼反饋多項(xiàng)式。仿真實(shí)驗(yàn)驗(yàn)證了所提方法的有效性,該方法無需遍歷搜索反饋多項(xiàng)式,且具有較好的魯棒性,所需數(shù)據(jù)量小,隨著數(shù)據(jù)量的增大和擾碼階數(shù)的降低,其識(shí)別正確率逐漸提高。
