多小區(qū)聯(lián)合檢測(cè)（MCJD）是針對(duì)TD系統(tǒng)內(nèi)干擾而設(shè)計(jì)的同頻干擾消除算法。當(dāng)TD用戶數(shù)超過一定負(fù)荷后，為了平衡強(qiáng)干擾帶來的性能下降，小區(qū)間可能會(huì)發(fā)生功率的相互攀升，造成網(wǎng)絡(luò)行那個(gè)的損失和終端發(fā)射功率的浪費(fèi)。所以小區(qū)邊界用戶雖少，但是影響巨大，改善小區(qū)邊界用戶的性能對(duì)提高切換成功率具有決定性作用，考慮到TD系統(tǒng)的特點(diǎn)，可以對(duì)多小區(qū)的同頻用戶進(jìn)行干擾消除。多小區(qū)聯(lián)檢實(shí)現(xiàn)基礎(chǔ)有:
1、RNC定時(shí)通過IUB口下發(fā)鄰區(qū)的上行碼數(shù)更新消息給NodeB；
2、NodeB收集鄰區(qū)上行的用戶碼，將鄰區(qū)干擾信號(hào)當(dāng)作已知信號(hào)，進(jìn)行聯(lián)合檢測(cè)；
3、由于NodeB和RNC之間的鄰區(qū)信息更新較大，所以必須增加專用的傳輸通道；
4、完成同頻多小區(qū)算法需要得到相鄰小區(qū)的完整的結(jié)構(gòu)化信息，包括Midamble碼、擾碼、擴(kuò)頻碼等。
該算法功能正常，對(duì)抑制同頻干擾有一定作用，但是聯(lián)檢的增益受負(fù)荷影響較大，高負(fù)荷下作用不明顯。
開通腳本如下：
1、傳輸增加CCP，利用CME工具生成
RNC側(cè)：
增加新的流量索引，SAALLNK或者SCTPLNK，TCCP,需要工具制作
