摘要

针对QAM通信系统中的盲相位恢复问题,提出了一种基于多模量的自适应算法。给出了稳态点、灵敏度、稳态失调、收敛时间和跟踪能力的分析。与已有的两种自适应算法进行了比较,结果表明,该算法在收敛时间和稳态抖动方面具有更好的性能,但代价是复杂度的降低。

An Adaptive Method for Blind Carrier Phase Recovery in a QAM Receiver
New multimodulus-based adaptive algorithms are being devised for blind phase recovery in QAM communication systems. Analysis of stationary points, sensitivity, steady-state misadjustment, convergence time and tracking ability are being provided. The proposed algorithm is compared with two existing adaptive algorithms and it is shown that the proposed algorithm can provide much better performance in terms of convergence time and steady-state jitter at the cost of complexity.
