Mc - cdma是将多载波技术应用于cdma中，兼具cdma和ofdm这两种技术的特点。在mc - cdma中，用户的信息符号先经过扩频、加扰，再将扩频序列的码片并行地在多个子载波上传输。 | | 6. | But the frequent use of training sequence is certainly a waste of channel bandwidth . research shows that with the prior knowledge of only the signature waveform and timing of the user of interest , blind adaptive multiuser detector can effectively detect data symbol of the desired user without training data sequence for every active user
在传统多用户检测技术基础上，自适应多用户检测利用训练序列在仅知道期望用户地址pn码及其定时信息条件下就可以进行检测，不足的就是训练序列占用了额外的频率资源。 | | 7. | Due to the multi - carrier transmission technology used in mc - cdma systems , almost all the previous synchronization algorithms in mc - cdma systems are derives from that in ofdm systems . they are suitable for ofdm systems , but they are not optimal for mc - cdma systems . the data symbols transmitted in mc - cdma systems have form of cdma signal , which is greatly different from normal binary signal
传统的各种mc - cdma同步算法主要还是借鉴了ofdm的同步算法，本文提出采用用户扩频码作idft后在fft之前作同步，充分利用了ofdm信号中所包含的mc - cdma信号形式，它与纯粹的ofdm传输的二进制数据不同，它与pn序列具有更好的相关性。 |
