In MC-DS-CDMA systems,the optimization of both carrier spacing and chip waveform can reduce the system multi-access interference.
通过对MC-DS-CDMA系统中多址干扰(MAI)的研究,提出了运用最优化波形结合最优化载波间距来减小系统多址干扰的方法。
The error performance of the proposed scheme is derived,which shows that full diversity—frequency and space diversity can be obtained and optimal subcarrier interleaving separation can be searched to obtain larger coding gain if the transmitter has the knowledge of space correlation and delay profile of the channel.
详尽推导了该空时频码的误码性能,表明它可以获得全部的分集增益——空间分集以及频率分集,并且在发送端已知信道的空间相关特性以及时延谱时可以找出优化的子载波交织间距来增大码增益。
