若干种垂直分层空时码检测算法的研究及其性能比较
Study of several detection algorithms for VLST receiver and their performance comparison
分层空时编码（LST：Layered Space-Time code）是一项有效提高MIMO信道容量的技术。它能有效提高频谱利用率以及无线信道传输速率。因此，LST成为4G中一项核心技术。而垂直LST（VLST）接收机结构中采用的检测算法是干桡抑制和干扰消除的联合过程。本文研究的迫零算法（ZF）和最小均方误差算法（MMSE）是用于干扰抑制的两种常用检测算法，并结合考虑了干扰抵消技术，文中对算法的实现进行了数学推导。最后对空时分层接收机采用不同接收方案系统性能（也就是误码率BER）也进行了仿真比较和分析。
Layered space-time code (LST) technique, which can enhance the channel capacity of MIMO systems and increase the spectrum efficiency and data rate effectively, has become a key technique for the 4G systems. The detection algorithms for the vertical LST (VLST) receiver are mostly combinations of interference suppression (IS) and interference cancellation (IC). Two conventional methods for IS, i.e., the zero forcing (ZF) and the minimum mean square error (MMSE) algorithms, are considered in this paper and presented in combination with IC. The mathematical derivation are introduced accordingly. In the end, the system performance of different receiver schemes are simulated and compared with each other.
