Synchronization acquisition technique is one of the most important techniques in any communication systems . in mc - cdma system , we exploit multi - carriers to transmit high - speed data , which is sensitive to the errors of synchronization , so synchronization is important , especially fast acquisition 在mc - cdma系統(tǒng)中,利用多個(gè)載波傳輸數(shù)據(jù),并且傳輸?shù)氖歉咚贁?shù)據(jù),它對(duì)系統(tǒng)的同步錯(cuò)誤非常敏感,所以同步技術(shù)就顯得尤其重要,而且要求能夠快速捕獲。
