摘要 为了解决在Turbo均衡中由迭代引起的均衡延迟问题,两种分别对应于最大后验概率(MAP)和线性最小均方误差(LMMSE)均衡算法的并行均衡方案被提出。通过理论分析、仿真验证以及最后的硬件实现复杂度的分析研究表明,对于上述两种并行均衡方案,可以保证在小的硬件实现复杂度开销以及几乎没有性能损失的前提下,大大降低其均衡延迟。 In order to reduce the equalization delay induced by iteration, two parallel methods were proposed respectively based on maximum a-posteriori probability (MAP) and linear minimum mean-squared error (LMMSE) equalization algorithm in Turbo equalization. Through theoretical analysis, simulation and hardware complexity discussion, it is concluded that the proposed two parallel equalization schemes can fully reduced the equalization delay with small hardware complexity and excellent performance.
