title = "Principal Component Reconstruction of Odd-bit QAM Signals for Performance Improvement of Principal Component-based Phase Estimation Algorithm in Coherent Optical Communications",
abstract = "We propose a principal component reconstruction scheme based on clustering and partial-scaling for phase recovery of odd-bit QAM signals, which can achieve up-to 0.18 and 1.31 bit/symbol MI gain for high-speed 32QAM and 128QAM signals.",
