空时编码的MIMO系统中空时SIC多用户检测

The Space-Time Successive Interference Cancellation Multiuser Detection in Space-Time Block Coded MIMO Systems

针对空时编码的多输入多输出系统,对传统的串行干扰对消算法进行了改进,提出了空时两步法连续干扰对消多用户检测方法.通过使所有用户进行全干扰对消,从而检测期望用户的信号并抑制多址干扰.模拟结果表明,该方法和其他的多用户检测方法相比具有一定的优越性.

This paper presented a space-time two-step successive interference cancellation multiuser detection scheme in space-time block coded （STBC） multiple-input multiple-output （MIMO） systems., After making all users benefit from full interference cancellation, the desired user is detected and multi-access interference （MAI） is suppressed. The simulation results illustrate that the proposed scheme outperforms the other multiuser detection methods.
