垂直分层空时码(VLST)检测算法研究
he Study on Detection Algorithms of Vertical Layer Space-Time Codes (VLST)
MIMO系统中VLST（垂直分层空时码）是一种重要的码结构。VLST的检测算法在整个系统的性能提升上具有重要的作用。本文主要介绍了MIMO系统和VLST的结构，并对VLST接收机采用的进行了干扰抑制（IS）和干扰消除（IC）的三种接收检测算法：迫零算法(ZF)、QR算法和最小均方误差算法(MMSE)进行了研究。对比只采用干扰抑制的迫零（ZF）算法和最小均方误差算法（MMSE），我们对上述3种算法进行了仿真分析，并对采用干扰抑制和消除的ZF和MMSE检测算法的系统在不同的收发天线数组合方式下进行了性能仿真和分析，最后得出结论。
he Vertical Layer Space-Time Code (VLST) is an important code structure in MIMO system. The VLST detection algorithm is crucial for the system performance. In this paper, we study the structures of both MIMO and VLST, and we make discussions on the algorithms of ZF, QR and MMSE which are based on both Interference Suppressing and Interference Canceling. Comparing with the ZF and MMSE based on only Interference Suppressing, we make simulations to compare the performances of the above algorithms. The performances of different pairs of transmitting and receiving antenna are also simulated, which in the end lead to the final conclusions.
