An Adaptive Method for Blind Carrier Phase Recovery in a QAM Receiver
Shafayat Abrar · 2007
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.
