Proposes a novel channel estimation algorithm for multi - carrier code division multiplex access ( mc - cdma ) systems on the uplink
摘要提出了一種新穎的適用于多載波碼分多址接入( mc - cdma )系統(tǒng)上行鏈路的通道估計(jì)算法。
Multicarrier wireless communications have been widely investigated in the past decades . recently , two - dimensional spread spectrum ( 2d - ss ) system has drawn a lot of attention because of its full utilization of spreading characteristics in the frequency domain and time domain . compared with multicarrier code division multiplex access ( mc - cdma ) , 2d - ss system can effectively mitigate multiple access interference ( mai ) due to spreading in the time domain
當(dāng)前多載波無(wú)線通信技術(shù)得到了廣泛的研究,二維擴(kuò)頻通信系統(tǒng)是近年來(lái)提出的新的擴(kuò)頻通信方式,由于二維擴(kuò)頻系統(tǒng)從時(shí)域和頻域上分別對(duì)數(shù)據(jù)信號(hào)進(jìn)行頻譜擴(kuò)展,因此它同時(shí)具有時(shí)域擴(kuò)頻和頻率擴(kuò)頻通信系統(tǒng)的特點(diǎn),是對(duì)傳統(tǒng)的一維時(shí)域直接序列擴(kuò)頻和多載波擴(kuò)頻的推廣。
