| 摘 要： | 研究了基于LS码的分布式MIMO-CDMA系统结构,提出了广义的分布式MIMO系统的信道模型,给出了采用MIMO技术时发射机和接收机的结构.最后以单小区双天线的三基站收发端分布式网络为例,仿真了不同的扩频序列、基站收发端的数目和多天线与系统性能的相互关系.结果表明使用LS码扩频的分布式MIMO-CDMA系统性能比使用Walsh码扩频的MIMO-CDMA系统性能优越,基站收发端或移动台采用多天线时的性能优于单天线.

| Abstract: | This paper proposes a distributed MIMO-CDMA structure with LS code.Under the initial assumption of independent degradations to the ends of base station transceiver and mobile unit antenna,a channel model for distributed MIMO-CDMA is developed,and furthermore the structures of transmitter and receiver with multi-antennas are given.A double antenna,single cell wireless network adopting MIMO system is used as example to simulate the relationship between different spread spectrum sequences,quantity of base stat... |
