摘 要: | 未来的移动通信系统要求提供的数据传输速率将高达100Mb/s以上,支持的业务也将从语音业务扩展到多媒体业务(包括实时的流媒体业务)。该文提出采用m序列的不同循环移位来构建CCSK序列,并在前导CAZAC序列上叠加CCSK序列,以用于隐含承载接入信息。为了减少两个序列之间的相互影响,调整两种序列之间的能量比例以及采用干扰消除,将显著提高两种序列的检测性能。

Abstract: | The data transmission rate will be update to 100 Mb/s in future mobile communication system, which require to supply multimedia traffic. So, high spectrum effective and great capacity techniques need to be researched. In this paper, we put forward a random access information bearing method, in which a constant amplitude zero auto-correlation (CAZAC) sequences is added by a cyclic code shift keying (CCSK) sequences, and the CCSK sequences are constructed by circle shifting of m sequences. With the method, th... |
