摘要

我们提出了一种降低复杂性的MIMO MMSE-DFE系数计算算法，该算法基于对N. Al-Dhahir和A.H. Sayed(2000)开发的快速块算法的改进。通过消除不必要项的计算，我们已经将复杂性降低了近50%。考虑了有限精度算法对信噪比的影响，最小定点字长为32位不会导致明显的性能损失。硬件实现问题取决于几个因素，并对这些因素进行了讨论

Reduced Complexity MIMO MMSE-DFE

We present a reduced complexity MIMO MMSE-DFE coefficient computation algorithm which is based on an improvement to the fast block algorithm developed in N. Al-Dhahir and A.H. Sayed (2000). We have achieved a nearly 50% reduction in complexity by eliminating the computation of unnecessary terms. The effects due to finite precision arithmetic on SNR are also considered and a minimum fixed-point word length of 32 bits results in no noticeable performance loss. Hardware implementation issues depend on several factors and these are also discussed
